Parameter Function Setting
P3353[0...2] Super torque ramp time [s] This parameter defines the ramp time to be used when ramping
up to the super torque frequency.
Range: 0.0 ... 650.0 (factory default: 5.0)
P3354[0...2] Super torque frequency [Hz] This parameter defines the frequency at which the additional
boost is applied for super torque mode.
Range: 0.0 ... 599.0 (factory default: 5.0)
P3355[0...2] Super torque boost level [%] This parameter sets the temporary boost level for super torque
mode.
It applies boost in [%] relative to P0305 (rated motor current)
once the super torque frequency has been reached for the time
specified in P3356.
Range: 0.0 ... 200.0 (factory default: 150.0)
P3356[0...2] Super torque boost time [s] This parameter sets the time for which the additional boost is
applied, when the output frequency is held at P3354.
Range: 0.0 ... 20.0 (factory default: 5.0)
Function diagram
Description:
The Super Torque mode is enabled when an ON command is issued, and the following
sequence is performed:
● Ramps up to P3354 Hz with the boost level specified by P1310, P1311, and P1312
● Maintains for P3356 s with the boost level specified by P3355
● Reverts boost level to that specified by P1310, P1311, and P1312
● Reverts to "normal" setpoint and allows output to ramp using P1120
