General Information

Important Safety Warnings

WARNING

HIGH VOLTAGE
The ISD 410 servo system contains components that operate at a high voltage when connected to the electrical supply network. A hazardous voltage is present on the servomotors, the power supply module and the connection box whenever they are connected to the mains network. There are no indicators on the servomotor that indicate the presence of mains voltage. This indication is provided on the connection box. Installation, commissioning and maintenance may only be performed by qualified staff. Incorrect installation, commissioning or maintenance can lead to death or serious injury.

WARNING

UNINTENDED START
The ISD 410 servo system contains servomotors that are connected to the electrical supply network and can start running at any time. This may be caused by an external switch, a CAN bus command, a reference signal, or clearing a fault condition. Servomotors and all connected devices must be in good operating condition. A deficient operating condition may lead to death, serious injury, damage to equipment or other material damage when the unit is connected to the electrical supply network. Take suitable measures to prevent unintended starts.

WARNING

DISCHARGE TIME
The servomotors, the connection box and the power supply module contain DC link capacitors, that remain charged for some time after the mains supply is switched off at the power supply module.
To avoid electrical shock, fully disconnect the power supply module from the mains before carrying out any maintenance on the ISD servo system or its components. Wait for at least the time listed below before carrying out maintenance work:

Note: High voltage may still be present even if the LED on the ISD connection box is not lit!

Introduction

System Overview

• The servomotors are self-contained distributed drives, which means that the drive electronics are housed together with the motor in the same casing. The motion control software also runs independently in the servomotor; which reduces the load on the higher-level control system.
  A master system controls the servomotors. In this system servomotors operated in a DC group are controlled by a master system.

Several motors can be operated in a group using a hybrid cable. This cable carries the DC supply voltage and the CAN bus signals. The ISD 410 servo system is designed to accommodate up to 60 ISD 410 servomotors and consists of:

• 1 Power supply module
• 1 Connection box
• 1 Encoder Box
• Servomotors
• 1 Master
• Hybrid cables

NOTE
The ISD 410 servomotors cannot be used in other servo systems from other manufacturers!
Motors from other manufacturers cannot be used in the Danfoss ISD 410 servo system!

Safety Instructions and Precautions for the ISD 410 Servo System

Read the safety instructions carefully before starting to work in any way with the servo system. Compliance with the safety instructions and precautions is necessary at all times.

• Orderly and proper transport, storage, fitting and installation, as well as careful operation and maintenance, are essential for the trouble-free and safe operation of this servo system and its components.
• Only suitably trained and qualified staff may work on the servo system and its components or in its vicinity. See Chapter 3.4 Qualified Personnel.
• Use only accessories and spare parts approved by the manufacturer.
• Comply with the specified ambient conditions.
• The information in these operating instructions about the use of available components is provided solely by way of examples of applications and suggestions.
• The plant engineer or system engineer is personally responsible for checking the suitability of the supplied components and the information provided in this document for the specific application concerned:
  • for compliance with the safety regulations and standards relevant to the specific application concerned.
  • for implementing the necessary measures, changes and extensions.
• Commissioning the servo system and its components is not allowed until it has been ascertained that the machine, system or plant in which they are installed conforms to the statutory provisions, safety regulations and standards that apply in the country of use to that application.
• Operation is allowed only in compliance with the national EMC regulations for the application concerned.
• See the VLT® ISD 410 Design Guide for information regarding EMC-compliant installation of the servo system.
• Compliance with the limit values specified by national regulations is the responsibility of the producer of the plant, system or machine.
• Compliance with the specifications, connection conditions and installation conditions in this instruction manual is mandatory.
• The safety regulations and safety provisions of the country in which the equipment is used must be observed.
• Care must be taken to ensure that orderly protective earthing of the equipment, which protects the user against the supply voltage and protects the power supply module against overload, is performed by local and national regulations.
• Overload protection for the servomotor can be programmed using the master system. For more information, see Programming in the VLT® ISD 410 Design Guide.
• Do not remove or replace the SD card on the encoder box during operation, otherwise the contents of the SD card could be destroyed. Switch the encoder box off and wait 10 seconds before removing the SD card.

WARNING

EARTHING HAZARD
For reasons of operator safety, the components of the servo system must be earthed correctly by national or local electrical regulations and the information in these operating instructions. The earth leakage current is greater than 3.5 mA. Improper earthing of the servomotor may result in death or serious injury.

Operational Safety

• Safety-related applications are allowed only if they are explicitly and unambiguously mentioned in the VLT® ISD 410 Design Guide. Otherwise, they are not allowed.
• All applications that can cause hazards to people or property damage are safety-related.
• The stop functions implemented in the software of the master system do not interrupt the mains voltage supply to the power supply module and are therefore not allowed to be used as safety switches for the servo system.
• The motor can be brought to a stop by a software command or a zero-speed setpoint, but DC voltage remains present on the servomotor and/or mains voltage in the power supply module. If personal safety considerations (e.g. risk of personal injury caused by contact with moving machine parts after an unintended start) make it necessary to ensure that an unintended start cannot occur, these stop functions are not sufficient. In this case, the servo system must be detached from the mains network or a suitable stop function must be implemented.
• When the servomotor is stopped, it may start up again on its own if the circuitry of the servomotor is defective or after the elimination of a temporary overload, a problem with the supply voltage or a problem with the servomotor. If personal safety considerations (e.g. risk of personal injury caused by contact with moving machine parts after an unintentional start) make it necessary to ensure that an unintended start cannot occur, the normal stop functions of the servomotor are not sufficient. In this case, the servo system must be disconnected from the mains network or a suitable stop function must be implemented.
• The servo motor may start running unintentionally during parameter configuration or programming. If this can pose a risk to personal safety (e.g. risk of personal injury due to contact with moving machine parts), unintended motor starting must be prevented, for example by using the Safe Stop function or by safe disconnection of the servomotors.
• Do not disconnect the cables from the servomotor while the servo system is connected to the mains voltage. Ensure that the mains supply is disconnected and the required waiting time has elapsed before disconnecting or connecting the hybrid cable or disconnecting cables from the connection box and/or the power supply module.
• In addition to the L1, L2 and L3 supply voltage inputs on the power supply module, the servo system has other supply voltage inputs, including external DC 24 V. Before commencing repair work, check that all supply voltage inputs have been switched off and that the necessary discharge time for the intermediate circuit capacitors has elapsed.
• The supply of power to the servo system must be switched off for repair work. Before disconnecting or connecting the hybrid cable or disconnecting cables from the connection box and/or the power supply module, ensure that the mains supply is disconnected and the necessary discharge time has elapsed.

WARNING

DISCHARGE TIME
The servomotors, the connection box and the power supply module contain DC link capacitors, that remain charged for some time after the mains supply is switched off at the power supply module.
To avoid electrical shock, fully disconnect the power supply module from the mains before carrying out any maintenance on the ISD servo system or its components. Wait for at least the time listed below before carrying out maintenance work:

Note: High voltage may still be present even if the LED on the ISD connection box is not lit!

CAUTION
Never connect or disconnect the hybrid cable to or from the servomotor when voltage is present. Doing so will damage the electronic circuitry. Observe the discharge time for the DC link capacitors.
