Data type
Torque limitation in motor mode and in generator mode
• These input signals are directly transferred to the motor control to limit the
controller's maximum torque in motor and generator mode.
INT
• The drive cannot output a higher torque in motor/generator mode than set here.
• The applied values (any polarity) are internally interpreted as absolute values.
• If V/f characteristic control (VFCplus) is selected, limitation is indirectly
performed via a so-called I
• If sensorless vector control (SLVC) or servo control (SC) is selected, limitation has
a direct effect on the torque-producing current component.
• Scaling: 16384 ≡ 100 % M

Change of direction of rotation
• For instance if a motor or gearbox is fixed laterally reversed to a machine part, but
BOOL
the setpoint selection should still be executed for the positive direction of
rotation.
FALSE Direction of rotation to the right (Cw)
TRUE Direction of rotation to the left (Ccw)
Activate clockwise rotation (fail-safe)
• For a detailed functional description see the
BOOL
FALSE Quick stop
TRUE Clockwise rotation
Activate counter-clockwise rotation (fail-safe)
• For a detailed functional description see the
BOOL
FALSE Quick stop
TRUE Counter-clockwise rotation
Main speed setpoint
• Offset and gain of this input signal can be set in
INT
signal adjustment of a setpoint encoder.
• Scaling: 16384 ≡ 100 % reference speed (C00011)
• The main setpoint is transformed to a speed setpoint in the setpoint encoder via
a ramp function generator with linear or S-shaped ramps.
• Upstream to the ramp function generator, a blocking speed masking function
and a setpoint MinMax limitation are effective.
• For a detailed functional description see the
Additional speed setpoint
• Offset and gain of this input signal can be set in
INT
signal adjustment of a setpoint encoder.
• Scaling: 16384 ≡ 100 % reference speed (C00011)
• The additional speed setpoint can be linked arithmetically with the main speed
setpoint behind the ramp function generator.
• The additional speed setpoint can be shown via ramp times of a second ramp
function generator.
• For a detailed functional description see the
L
controller.
