Danfoss MA01c iC2-Micro Frequency Converters

Product Information: iC2-Micro Frequency Converters

The iC2-Micro Frequency Converters are AC drives that are designed for use by qualified personnel for installation and commissioning purposes. The product comes with an Operating Guide that provides essential information needed to use the drive safely and professionally. The product is not to be disposed of with domestic waste containing electrical components; it should be collected separately in accordance with local and currently valid legislation.

Safety
It is important to pay particular attention to the safety instructions and general warnings provided in the Operating Guide to avoid the risk of death, serious injury, and equipment or property damage. The AC drives contain high voltage when connected to AC mains input, DC supply, or load sharing. Leakage currents of the drive exceed 3.5 mA, so it is important to ensure that the minimum size of the ground conductor complies with local safety regulations for high touch current equipment.

Installation
The product has mechanical dimensions that include enclosure size, height, width, depth, and mounting holes. The product comes in different enclosure sizes and power options ranging from 1.0 kW (2.4 hp) to 1.6 kW (3.5 hp). The maximum weight of the product varies according to the enclosure size and power option selected. The product comes with a potentiometer on the local control panel that extends 6.5 mm (0.26 in) from the drive.

Connecting to Mains and Motor
When connecting the product to mains and motor, use 6.3 mm (0.25 in) insulated connectors designed for high voltage for DC (load sharing and brake). Refer to the drive’s Design Guide or contact Danfoss for further information on load sharing and brake. The product has terminals for load sharing and brake that require specific connector types. Ensure that the terminal cover is removed with a screwdriver before connecting the wires.

Overview of Control Terminals

The product has a RJ45 port that complies with Modbus 485 protocol for connection to external devices. The product has control terminals that are configured in PNP-configuration with factory setting (speed control mode) and include +24 V OUT, Start, Reverse, Reset (DI), Jog, GND, 0-20 mA 1K Ohm, 0-10 V GND, Frequency output, Reference, and Function: Fault.

Safety

Pay particular attention to the safety instructions and general warnings to avoid the risk of death, serious injury, and equipment or property damage.

WARNING

• HIGH VOLTAGE
  AC drives contain high voltage when connected to AC mains input, DC supply, or load sharing.

• UNINTENDED START
  The motor may start from control panel, I/O inputs, fieldbus, or MyDrive® Insight at any time, when the drive is connected to the AC mains, DC supply, or load sharing.

• DISCHARGE TIME
  The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be present even when the warning indicator lights are off.

  • Stop the motor, and disconnect AC mains, permanent magnet type motors, and remove DC-link supplies, including battery back-ups, UPS, and DC-link connections to other drives.
  • Wait for the capacitors to discharge fully and measure it before performing any service or repair work.
    The minimum waiting time is 4 minutes for MA01c, MA02c, MA01a, and MA02a drives, and 15 minutes for MA03a, MA04a, and MA05a drives.

• LEAKAGE CURRENT
  Leakage currents of the drive exceed 3.5 mA. Make sure that the minimum size of the ground conductor complies with the local safety regulations for high touch current equipment.

Installation

Mechanical Dimensions

Note:

1. Including decoupling plate.
2. The potentiometer on the local control panel extends 6.5 mm (0.26 in) from the drive.
3. Not including decoupling plate.

Connecting to Mains and Motor

• Mount the ground wires to the PE terminal.
• Connect motor to terminals U, V, and W.
• Mount mains supply to terminals L1/L, L2, and L3/N (3-phase) or L1/L and L3/N (single-phase) and tighten.
• For required maximum screwing torque, see the back of terminal cover.

Load Sharing/Brake
Use 6.3 mm (0.25 in) insulated connectors designed for high voltage for DC (load sharing and brake).
Contact Danfoss or refer to the drive’s Design Guide.

Recommended connector type (only for drives below 7.5 kW/10 hp): Ultra-Pod Fully Insulated FASTON Receptacles and Tabs, 521366-2, TE connectivity.

NOTICE
Voltage levels of up to 850 V DC may occur between terminals +UDC/+BR and -UDC. Not short-circuit protected.

Control Terminals

• All control cable terminals are located underneath the terminal cover in front of the drive.
• See the back of the terminal cover for outlines of control terminals and switches.

NOTICE
Remove the terminal cover with a screwdriver, see illustration 2.

RJ45 Port and RS485 Termination Switch

• iC2-Micro drive has a RJ45 port which complies with Modbus 485 protocol.

The RJ45 port is used for connecting:

• External control panel.(1)
• PC tool (MyDrive® Insight) via an adapter.(1)
• Offline configuration tool for parameter settings when the drive is not powered on.(1)

Note : (1) The tool is not available currently.

NOTICE

• The RJ45 port supports up to 3 m (9.8 ft) of shielded CAT5e cable which is NOT used to directly connect the drive to a PC. Failure to follow this notice causes damage to the PC.
• RS485 termination switch should be set to ON if the drive is at the end of the fieldbus.
• Do not operate RS485 termination switch when the drive is powered on.

Programming

Control Panel

Table 3: Status and Operating Indicator Lights

Operation with Control Panel
After the drive is powered up, press the Home/Menu key to toggle between status display and main menu.
Use the Up/Down keys to select items, and press the OK key to confirm selection.

Note:

• (1) Local mode only.
• (2) Remote mode only.
• (3) The status is only shown when the corresponding function is enabled.
• (4) For AMA execution, refer to chapter Automatic Motor Adaptation (AMA). If parameter P5.4.3 Motor Control Principle is set as [0] U/f, no need to execute AMA.

Illustration 6: Operation with Control Panel

Automatic Motor Adaptation (AMA)

• Via running AMA in VVC+ mode, the drive builds a mathematical model of the motor to optimize compati- bility between drive and motor, and thus enhances the motor control performance.
• Some motors may be unable to run the complete version of the test. In that case, select [2] Enable Reduced AMA in parameter P4.2.1.3 AMA Mode.
• AMA completes within 5 minutes. For best results, run the following procedure on a cold motor.

Procedure:

1. Set motor data according to the motor nameplate.
2. If needed, set motor cable length in parameter P4.2.1.4 Motor Cable Length.
3. Set [1] Enable Complete AMA or [2] Enable Reduced AMA for parameter P4.2.1.3 AMA Mode, the main display shows To start AMA, see illustration 7.
4. Press the Start key, the test runs automatically and the main display indicates when it is completed.
5. When AMA is completed, press any key to exit and return to normal operation mode.

Troubleshooting

Table 6: Warning and Fault Events Summary
