overexcitation brake is disabled, the Decel current of motor will decrease and the Decel time
will be prolonged.
b1-18
Dynamic brake
Range: 0~1
Factory default: 0
0: Disabled
1: Enabled
When dynamic brake is enabled, the electric energy generated during Decel shall be
converted into heat energy consumed by brake resistor, so as to attain rapid Decel. This
brake method applies to brake of high-inertia load or the situations that require quick stop. In
such a case, it is necessary to select appropriate dynamic brake resistor and brake unit. The
drives equal and below 15kW are provided with a standard built-in brake unit. Built-in brake
chopper is optional for drives 18.5kW~75kW.
b1-19
Dynamic brake
threshold voltage
Range: 650V~750V
Factory default:
720V
This parameter takes effect only to the drives with built-in brake chopper. If b1-18 is set to 1:
when bus voltage of drive attains the value of b1-19, dynamic brake shall perform. The energy
shall be rapidly consumed through brake resistor. This value is used to regulate the brake
effect of brake chopper.
b1-20
Auto restart when power up
again after power loss
Range: 0~1
Factory default: 0
Defines the drive status when power up again after power loss during running
0: Disabled
The drive will not run automatically when power is up after power loss.
1: Enabled.
When run command is controlled by control panel or communication, the drive will run
automatically when power is up again after power loss. When run command is controlled by
terminals, the drive will run automatically only if ON signal from run command terminal is
detected
ATTENTION:
Enable this parameter with caution for safety consideration.
b1-21
Time delay of auto restart
when power up again
Range: 0.0s~10.0s
Factory default:
0.0s
This time setting should consider work restoration time of relative devices in the system when
power is up again after power loss, on the premise that b1-20 is set to 1.
