T03
HOLD TIME on STARTUP
Min: 0.1 s
Max: 5 s
Default: 0.3 s
Driver does not starts to rotate motor when mechanical brake releases. Slip may happen due to weight
difference on brake releasing. To overcome slip on startup, driver holds motor during zero speed period
between end of [T01] period to end of [T03] period. Acceleration starts after this period.
T04
START SPEED RAMP
Min: 0.1 s
Max: 5 s
Default: 0.4 s
Motor hold process finished at the end of [T03] period and motion starts. Reference speed rise to [S09]
speed until this parameter period. If [T04] increase, acceleration of start speed will decrease; if
decrease, acceleration of start speed will increase.
[T04] parameter is disabled if [S09] parameter is set to 0.
T05
START SPEED WAIT PERIOD
Min: 0.1 s
Max: 5 s
Default: 0.3 s
This parameter assigns the period of reference speed waits at [S09] speed. At the end of this period,
system accelerates with the acceleration parameter.
[T05] parameter is disabled if [S09] parameter is set to 0.
8.2.2 Timings on Stopping
Stopping phase starts when the motor speed is below [S17] parameter. Motor hold command triggers at
that point. After [T06] period, driver release brake contactor over BR output. [T07] triggers with the end
of [T06] period and drivers terminate motor outputs. After [T08] period, driver release main contactors
over MC output and pass no WAIT MODE.
T06
BRAKE RELEASE DELAY
Min: 0.1 s
Max: 5 s
Default: 0.2 s
Stopping phase triggers [T06] period and at the end of the period, driver release brake contactor over
BR output.
T07
DC BRAKE PERIOD
Min: 0.1 s
Max: 5 s
Default: 0.3 s
Driver has to hold motor until releasing of brake contactors. [T06] triggers [T07] period and motor hold
process is active until this period.
T08
CONTACTOR RELEASE DELAY
Min: 0.1 s
Max: 5 s
Default: 0.1 s
End of [T07] triggers [T08] period and at the end of the period, driver releases main contactors over MC
output and motion process finishes.
