5.6.1.3 Parameterising load adjustment
C00962 serves to parameterise a load adjustment in [%] proportionally to the rated torque to obtain
a correspondingly "rigid "drive behaviour even after the starting action.
• When starting torque = rated torque, a load adjustment of 50 % is suitable for most
applications.
The C00961 parameter serves to adjust the characteristic depending on the load at CW and CCW
rotation:
Short overview: Parameters for load adjustment

Stop!
If the load adjustment is too high, the motor current may increase in idle state and the
motor may overheat!
Setting in C00961 Info
0: CW rotation in motor mode/CCW rotation in motor
mode
The motor operates in motor mode in both directions.
1: CW rotation in motor mode/CCW rotation in
generator mode
Application example: Hoist without counterweight
2: CW rotation in generator mode/CCW rotation in
motor mode
Application example: Dancer-controlled unwinder
