Residual hazards

Residual hazards The user must take the residual hazards mentioned into consideration in the risk assessment for his/her machine/system. If the above is disregarded, this may result in injuries to persons and material damage!
DANGER! Dangerous electrical voltage During operation and up to 20 minutes after power-off, hazardous electrical voltages may be present at the connections of the product. The leakage current against earth (PE) is > 3.5 mA AC or > 10 mA DC.
Possible consequences · Death or serious injury from electric shock
Protective measures · Any work on the product must only be carried out in a deenergized state. · Check that no voltage is present! · After switching off the mains voltage, observe the signs on the product. · After switching off, wait until the drive is at a standstill. · Implement the measures required by EN IEC 61800-5-1 or EN IEC 60204-1, i.e. fixed
installation and standards-compliant PE connection.
Degree of protection – Protection of persons and device protection Information applies to the mounted and ready-for-use state.
Motor protection With some settings of the inverter, the connected motor can be overheated. · E.g. via the operation of self-ventilated motors at low speeds over a long period. · E.g. by operating DC-injection braking over a long period.

Product Observe the warning signs on the product!
Dangerous electrical voltage Before working on the product, check whether all power connections are deenergized! After mains disconnection, the power terminals carry the hazardous electrical voltage for the time specified next to the symbol!
Electrostatic sensitive devices Before working on the product, the staff must ensure to be free of electrostatic charge.
High leakage current Carry out fixed installation and PE connection in compliance with the following standard: EN IEC 61800-5-1/EN IEC 60204-1
Hot surface Use personal protective equipment or wait until the device has cooled down!
Protection of the machine/system · Drives can reach dangerous overspeeds, e.g. from setting high output frequencies for
motors and machines which are not suitable. The inverters do not provide any protection against such operating conditions. Use additional external components for this purpose. · Only switch the contactor in the motor cable when the inverter is inhibited. Switching them when the inverter is enabled is only permissible when no monitoring components respond.
Motor In the event of a short circuit of two power transistors, a residual movement of up to 180°/ number of pole pairs on the motor may occur (e.g. 4-pole motor): Residual movement max. 180 °/2 = 90°).

EMC-compliant installation The drive system of inverter and drive comply with the EMC Directive 2014/30/EU if they are installed according to the specifications of CE-typical drive systems. These guidelines should also be followed in installations requiring FCC Part 15 or ICES 001 compliance. The structure at the installation location must support the EMC-compliant installation with shielded motor cables.
· Please use sufficiently conductive shield connections. · Connect the housing with shielding effect to the grounded mounting plate with a surface as
large as possible, e.g. of inverters and RFI filters. · Use central earthing points.
The following example shows the effective wiring.

NOTE

Overload Possible consequences: Irreversible damage to the brake resistor · Protect the brake resistor of the inverter against overload with suitable parameterization. · The thermostat of the brake resistor can be used to establish a safety shutdown to
disconnect the inverter from the mains.

Recommendation: Use intrinsically safe brake resistors to be able to dispense with a separate switch-off device (e.g. a contactor).

Short connection cables up to 0.5 m
Up to a cable length of 0.5 m, the cable for the brake resistor and that of the temperature monitoring can be twisted. This procedure reduces problems caused by EMC interference.

Long connection cables up to max. 5 m
The cable of the brake resistor must be shielded The maximum length is 5 m. For the temperature monitoring cable, twisting is sufficient.

Uncontrolled start-up Improper installation of the safety engineering system can cause an uncontrolled starting action of the drives. Possible consequences: Death or severe injuries · Safety engineering systems may only be installed and commissioned by qualified personnel. · All wiring must be EMC-compliant. · All control components (switches, relays, PLC, …) must comply with the requirements of EN
ISO 13849-1 and EN ISO 13849-2. · Switches, relays with at least IP54 enclosure. · Devices with a degree of protection less than IP54 must always be installed in a control
cabinet with a minimum protection class of IP54. · The wiring must be shielded. · It is essential to use insulated wire end ferrules for wiring. · All safety-relevant cables outside the control cabinet must be protected, e.g. by means of a
cable duct. · Securely eliminate short-circuits and crossed wires according to the specifications of
EN ISO 13849-2. · Please refer to EN ISO 13849-1 and EN ISO 13849-2 for all further requirements and
measures. · In the case of an external force effect on the drive axes, additional brakes are necessary. In
particular, please observe the effect of gravitational force on hanging loads! · For safety-related braking functions, use safety-rated brakes only. · The user must ensure that the inverter is only operated within the specified environmental
conditions in its intended application. Only by doing so can the specified safety-related characteristics be adhered to.

DANGER!
Automatic restart when the requirement of the safety function is disabled. Possible consequences: Death or severe injuries · You must implement external measures in accordance with EN ISO 13849-1 to ensure that
the drive only starts up again after an acknowledgment.

Information
Display of the actual output frequency. Display of the actual motor current. Display of the actual motor voltage. Error message. This selection enables a flexible assignment of the start, stop, and rotating direction commands with digital signal sources. This selection enables the motor to start exclusively via the start key of the keypad. Other signal sources for starting the motor are ignored. The setpoint is specified locally by the keypad. The setpoint is defined as analog signal via the analog input 1. The setpoint is defined as analog signal via the analog input 2. The digital inputs DI3 and DI4 can be configured as HTL input to use an HTL encoder as setpoint encoder or define the setpoint as a reference frequency (“pulse train”). The setpoint is defined as process data object via the network. For the setpoint selection, “preset” values can be parameterized and selected. All frequency presets are described in detail in the commissioning manual. After start command, the standard ramps are active. After start command, the “DC braking” function is active for the time set in P704.02. After the start command, the flying restart circuit is active. After start command, the standard ramps are active and the premagnetization of the motor is activated. This reduces the motor current and smoothes the acceleration curve during the starting process (only relevant in the V/f motor control mode). The motor has no torque (coasts down to standstill). The motor is brought to a standstill with the deceleration time 1 P221.00 (or deceleration time 2 P223.00 if activated). The motor is brought to a standstill with the deceleration time (P225.00) set for the “quick stop” function. Is similar to the stop method “standard ramp [1]”. Depending on the actual output frequency, however, the inverter delays the beginning of the down-ramping so that the number of motor revolutions until a standstill is reached and thus the stop position is always relatively constant.
Selection of the mains voltage for actuating the inverter.
Lower limit value for all frequency setpoints.

Disposal

If pollutants are disposed off improperly, they may cause a lasting damage to human health and the environment. Thus, electrical and electronic equipment must be collected separately from unsorted municipal waste so that it may be recycled or disposed of properly. If available, put the components to the company internal disposal from where it is passed on to specialized waste management companies. It is also possible to return the components to the manufacturer. For this purpose, please contact the customer service of the manufacturer. More detailed information on disposal can be obtained from the corresponding specialist firms and the competent authorities. The packaging of the component must be disposed of separately. Paper, cardboard and plastics must be recycled.
