What are recommendations of “use of motors in parallel” on ATV303 drive.
The drive rating must be greater than or equal to the sum of the currents of the motors to be controlled.
In this case, it is necessary to provide external thermal protection for each motor using probes or thermal overload relays.
It is advisable to install a motor under following situation:
- Three or more motors are connected in parallel,choke between the drive and the motors.
- When the motor cable length (L), including all of the cable tap (L1, L2 ... Lx),is greater than the allowed maximum motor cable length, shielded cable 25m,
non-shielded cable 50m.
