of flying start.
b1-12
Flying start 1 adjustment
coeff
Range: 0.0~100.0%
Factory default:
1.0%
When the start method is set to flying start (b1-05=2 or 3), a suitable flying start adjustment
coeff can suppress the output current during the process of flying start thus improve the
smoothness of flying start.
b1-13
Stop method
Range: 0~2
Factory default: 0
0: Ramp to stop
Upon the receipt of stop command, drive gradually decreases output frequency according to
the set Decel time, and stop when frequency attains 0.
1: Coast to stop
Upon the receipt of stop command, drive will immediately lock the output and the motor will
stop with its mechanical inertia.
2: Ramp to stop + DC brake
Upon the receipt of stop command, drive will decrease output frequency in accordance with
the rate of Decel time setting. Once the output frequency attains set value of b1-14, DC
braking will be enabled, and the drive will stop after the finish of DC braking.
b1-14
Start frequency of DC
brake stop
Range: 0.00Hz ~ upper limit
frequency
Factory default:
0.00Hz
b1-15
DC brake current
Range: 0.0%~200.0%
Factory default:
0.0%
b1-16
DC Brake time
Range: 0.00s~30.00s
Factory default:
0.00s
During the process “ramp to stop + DC braking", DC brake would be started when output
frequency attains the set value of b1-14. b1-15 defines brake level, in amps, applied to the
motor. 100% corresponds to rated current of drive. b1-16 sets the duration of time that DC
brake current works when b1-13 is set to 2. In case b1-16 is set to 0.0s, DC brake shall be
disabled.
If "DC brake stop" terminal is enabled, this terminal time duration or b1-16 set time, whichever
is longer, would be taken as stop brake time.
b1-17
Overexcitation brake
Range: 0~1
Factory default: 1
0: Disabled
1: Enabled
When overexcitation brake is enabled in case of stop by Decel, the motor shall transform the
electric energy generated during Decel into heat energy by increasing magnetic flux so as to
attain rapid stop. If this parameter is enabled, the Decel time will be shortened. If
