DRIVE PROGRAMMING 4-39
[0] SPEED CTR Speed control mode
The torque demand is equal to the speed loop output
M03P16.
[1] TORQ CONT Torque control
The torque demand is given by the sum of the torque
reference and the torque offset, if enabled. The speed is not
limited, however, the drive will trip if the speed exceeds the
OVERSPEED
threshold M03P23.
[2] TORQ SPD Torque limited speed control
The
SPEED LOOP OUTPUT
M03P16 defines the torque demand,
but is limited by the torque demand (M04P12 + M04P13).
The speed controller will try and accelerate the machine to
the final speed demand M03P11 level with a torque demand
defined by M04P13. This mode of operation can
be used when torque control is required, but maximum
speed must be limited.

HEN FINAL SPEED DEMAND
M03P11
IS
Positive:
- A positive torque demand (M04P12 + M04P13) will
provide torque control with a positive speed limit
defined by the
FINAL SPEED DEMAND
M03P11. A negative
torque demand ( M04P13) will provide torque
control with a negative speed limit defined by the Zero
Speed Threshold M03P20.
When
FINAL SPEED DEMAND
M03P11
IS NEGATIVE
:
- A negative torque demand will provide torque control
with a negative speed limit defined by the
FINAL SPEED
DEMAND
M03P11. A positive torque demand will provide
torque control with a positive speed limit defined by the
Zero Speed Threshold M03P20.
[4] TRQ FDFWD Speed control with torque feed-forward
The drive operates under speed control, with a torque
reference (M04P12 + M04P13) value added to the speed
controller output M03P16. This can be useful to improve
the regulation of some systems where the speed loop gains
need to be low.
M04P10 TORQUE OUTPUT
Indicates torque in the motor as % of rated torque.
Below rated frequency, the torque output is equal to the
torque-producing current relative to i
torq rated
.
Above rated frequency, the torque is compensated to
allow for the reducing flux in the motor.

Default:
M04P11 SYM CURRENT LIM
After having set the required value of maximum current in
M05P06, you may increase or decrease the percentage
overload current using M04P11. The maximum
percentage that can be set is limited by the overload
current rating of the drive. The limit applies when
motoring and regenerating.
The value of M04P11 is automatically reduced when the
value of M05P06 is increased beyond the default value.
