Control circuit wiring
16
Use twisted-pair cables for all drive control circuit wiring.
–
17
Ground the shields of shielded wiring to the GND terminal.
18
If using a 3-Wire sequence, set parameters for MFDI terminals S1 through S7, and properly wire control circuits.
19
Check for any other wiring mistakes. Only use a multimeter to check wiring.
–
20
Properly fasten the control circuit terminal screws in the drive. Refer to
21
Pick up all wire clippings.
–
22
Ensure that no frayed wires on the terminal block are touching other terminals or connections.
–
23
Properly separate control circuit wiring and main circuit wiring.
–
24
Analog signal line wiring should not exceed 50 m.
–
25
Safe Disable Input wiring should not exceed 30 m.
