Tip
ƒ
The minimum torque setpoint must not fall below 10 % (setting range 1 : 10).
ƒ
The motor may stall at operation with output frequencies < 3 Hz. If so, reset the
internal control by quickly switching the controller inhibit.
ƒ
If C0412/6 is combined with an analog signal source it is possible to display the
torque setpoint under C0047.
ƒ
If C0412/6 is not combined with an analog signal source (FIXED−FREE) it is possible
to select the torque setpoint under C0047. Please note:
– When disconnecting the mains, the value set will be lost!
– Before enabling the controller it is absolutely necessary at the restart to select the
correct setpoint under C0047. Otherwise the drive would start with the maximum
torque.
)
Note!
In the control modes "V/f characteristic control" and "vector control" the
signal combined with C0412/6 or C0047 act as a torque limitation.
