Illustration 21: Serial Communication Wiring Diagram
For basic serial communication set-up, select the following:
•
Protocol type in parameter 8-30 Protocol.
•
Drive address in parameter 8-31 Address.
• Baud rate in parameter 8-32 Baud Rate.
Two communication protocols are internal to the drive.
• Danfoss FC
• Modbus RTU
Follow motor manufacturer wiring requirements.
Functions can be programmed remotely using the protocol software and RS485 connection, or in parameter group 8-** Communica-
tions and Options.
Selecting a specific communication protocol changes various default parameter settings to match the specifications of the protocol
and makes extra protocol-specific parameters available.

4.10 Installation Check List

Before completing installation of the unit, inspect the entire installation as detailed in
completed.
Table 5: Installation Check List
Inspect for Description
Auxiliary equip-
• Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers, residing on the
ment
input power side of the drive, or output side to the motor. Ensure that they are ready for full-speed
operation.
• Check the function and installation of any sensors used for feedback to the drive.
• Remove any power factor correction capacitors on the motor.
• Adjust any power factor correction capacitors on the mains side and ensure that they are dampened.
Cable routing
• Ensure that the motor wiring and control wiring are separated, shielded, or in 3 separate metallic con-
duits for high frequency interference isolation.
Control wiring
• Check for broken or damaged wires and loose connections.
• Check that the control wiring is isolated from power and motor wiring for noise immunity.
• Check the voltage source of the signals, if necessary.
The use of shielded cable or twisted pair is recommended. Ensure that the shield is terminated correctly.
Cooling clear-
•
Ensure that the top and bottom clearance is adequate to ensure proper airflow for cooling, see chap-
ance
ter Mounting.
