Control cable

Control cables mainly include analog signal control cables and digital signal control
cables. Analog signal control cables use twisted double shielded cables with a separate
shielded twisted pair for each signal and different ground wires for different analog
signals. For digital signal control cables, a double-shielded cable is preferred, but
single-shielded or unshielded twisted pairs can also be used. For details, see section
Control cable.

4.2.2 Cable arrangement

Motor cables must be arranged away from other cables. The dU/dt of the VFD output may
increase electromagnetic interference on other cables. The motor cables of several VFDs
can be arranged in parallel. It is recommended that you arrange the motor cables, input
power cables, and control cables separately in different trays.
If a control cable and power cable must cross each other, ensure that the angle between
them is 90°. The cable trays must be connected properly and well grounded. The cable
trays must be connected properly and well grounded. Cable routing and routing distance
