5 . 4 5 T O R Q U E LIMIT
A . L 7 - 0 1 : Forward Torque Limit
L 7 - 0 2 : Reverse Torque Limit
L 7 - 0 3 : Forward Regenerative Torque Limit
L 7 - 0 4 : Reverse Regenerative Torque Limit
These parameters provide the ability to limit the amount of torque produced by the motor
in all four quadrants of operation: FWD motoring, REV motoring, FWD regen, and REV regen.
The torque limit functions as a torque current reference limit. Torque limit is active in both
speed mode and torque mode.
EXAMPLE:
L 7 - 0 1 Forward Torque Limit = 1 5 0 %
L 7 - 0 2 Reverse Torque Limit = 1 5 0 %
L 7 - 0 3 Forward Regenerative Torque Limit = 2 0 %
L 7 - 0 4 Reverse Regenerative Torque Limit = 2 0 %

SPEED FEEDBACK: Sfb.
SPEED REFERENCE: Sref.
During regeneration, the regeneration torque limits have been exceeded, thus the actual
speed (Sfb) doesn't follow the speed reference (Sref). This example also demonstrates the
accel/decel selection 1 ( H 1 - 0 6 data 7 ) .
