Motor overload protection The drive modules are provided with overload protection for the motor and the motor cable. For this to be effective, the drive overload protection parameter ‘Rated Current (00.046)’ must be set to the rated motor current as marked on the motor rating plate. For details of how to adjust the drive parameters, refer to the Unidrive M700, M701, M702 Control User Guide. -

- Page 48 4.22.2 Motor cable Use four core cable to connect the motor to the drive. Connect the ground core of the motor cable to the ground terminal of the motor. See Figure 4-8. A shielded cable may also be used. The shield of the motor cable should be connected to the ground terminal of the motor frame using a link that is as short as possible and not exceeding 50 mm (2 in) long.
- Page 49 Resolver connections: • Use a cable with an overall shield and twisted pairs. • Connect the cable shield to the drive 0 V connection by the shortest possible link. • It is preferable not to connect the cable shield to the resolver. However, in cases where there is an exceptional level of common-mode noise voltage present on the resolver body, it may be helpful to connect the shield at this point.

- Page 51 Terminal block in the enclosure The motor cable shields should be bonded to a back-plate using uninsulated metal cable-clamps which should be positioned as close as possible to the terminal block. Keep the length of power conductors to a minimum and ensure that all sensitive equipment and circuits are at least 0.3 m (12 in) away from the terminal block.
