Stop!
Motor and drive controller overload
The current controller parameters and the current limitation can be set
incorrectly and cause overloading of the motor and the drive controller.
Possible consequences:
ƒ The motor and the drive controller can be damaged within a very short
period of time.
Protective measures:
ƒ Before switching on the drive controller, ensure that the current controller
parameters and the current limitation are correctly set.
7.4.1 Overview

Stop!
Uncontrolled rotation of the motor
If the phase sequence is reversed in the motor or angle encoder cable, positive
feedback effects may occur resulting in the motor speed not being
controllable.
Possible consequences:
ƒ This may result in property damage.
Protective measures:
ƒ Before switching on the motor, check that the motor cable and the angle
encoder cable are connected in the correct phase relation.
The parameter set of the drive controller has to be adapted to the connected motor and to
the cable set used. This concerns the following parameters:
ƒ Rated current: Depends on the motor
ƒ Overload capacity: Depends on the motor
ƒ Number of poles: Depends on the motor
ƒ Current controller: Depends on the motor
ƒ Direction of rotation: Depends on the motor and on the phase sequence in the
motor cable and the angle encoder cable
ƒ Offset angle: Depends on the motor and on the phase sequence in the motor cable
and the angle encoder cable
This data has to be specified by means of the Small Drive Control program at the first use
of a motor type. For several motors, there are ready−made parameter sets available from
Lenze. Please observe that the direction of rotation and the offset angle also depend on the
cable set used.
