When frequency attains this value, digital output terminal "mechanical brake control" outputs
ON signal to control the open of mechanical brake. This value can be set the same value as
rated slip frequency of motor. Under V/f control, it could be set to a relatively large one.
E0-07
Mechanical brake open
current
Range: 0.0%~200.0%
Factory default:
120.0%
Current is limited to this value before the drive starts its acceleration from mechanical brake
open frequency, i.e. before mechanical brake mechanism is opened.
E0-08
Accel delay time after
brake open
Range: 0.0s~10.0s
Factory default:
1.0s
After digital output terminal "mechanical brake control" outputs ON 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 open of mechanical
brake.
E0-09
Mechanical brake FREQ
Range: 0.00Hz~10.00Hz
Factory default:
2.00Hz
Upon the receipt of stop command, the drive decelerates to mechanical brake close frequency
set by E0-09 and maintains constant-speed running at this frequency, waiting for the output of
mechanical brake control signal.
E0-10
Mechanical brake close
waiting time
Range: 0.0s~10.0s
Factory default:
0.0s
When the run frequency attains mechanical brake close frequency, after this waiting time,
digital output terminal "mechanical brake control" outputs OFF signal to control the mechanical
brake close.
E0-11
Mechanical brake close
holding time
Range: 0.0s~10.0s
Factory default:
1.0s
When the digital output terminal "mechanical brake control" outputs OFF signal, the frequency
will be maintained the time set by E0-11 to ensure complete mechanism close. Then, the drive
will block the output and stop.
Group E1 Protection Parameters
E1-00
Overvoltage stall
Range: 0~1
Factory default: 1
0: Prohibited
1: Allowed
When the motor is decelerating with a high-inertia load or short-term regenerative braking
