Accel delay time after
P40.08
contracting brake release
After digital output terminal "contracting brake control" outputs OFF signal, inverter will delay its
Accel with this time. Accelerated running will be started after this set time is elapsed. Please set
this parameter value in compliance with the time required for mechanism release of contracting
brake.
Contracting brake suction
P40.09
Upon the receipt of stop command, the drive decelerates to contracting brake suction
frequency set by P40.09 and maintains constant-speed running at this frequency, waiting for
the output of contracting brake control signal.
Contracting brake suction
P40.10
When the running frequency attains contracting brake suction frequency, after this waiting time,
digital output terminal "contracting brake control" outputs ON signal to control the contracting
brake suction.
Contracting brake suction
P40.11
When the digital output terminal "contracting brake control" outputs ON signal, the frequency
will be maintained the time set by P40.11 to ensure complete mechanism suction. Then, the
drive will block the output and stop.
Group P41 Protection Parameters
P41.00 Overvoltage stall
0: Prohibited
1: Allowed
When the motor is decelerating with a high-inertia load or short-term regenerative braking
occurs during the running, the energy feedback to the drive may raise DC bus voltage, and
thus resulting in overvoltage protection.
When this parameter value is set to 1, the drive will detect its bus voltage and compare
with parameter set by P41.01. If the bus voltage exceeds value of P41.01, drive output
frequency shall be adjusted instantaneously and the deceleration time shall be automatically
prolonged, to maintain the stability of DC bus voltage. Set this parameter to 0 if frequency
fluctuation or Decel time prolonging is not allowed.
