5.16.3 Closed loop settings
5.16.3.1 Start up torque
The start-up torque is used to generate torque against
thebrake so that when the brake is mechanically opened
therewill be no position change because the drive is
alreadygenerating the torque needed to keep the load in
place.

Brake fault response ID1316 “brake fault”
Defines the action after detection of a brake fault.
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to Stop Function
3 = Fault, stop mode after fault always by coasting
P1.15.11
1317
Brake fault delay “BrakeFaultDelay”
The delay before the brake fault (F58) is activated. Usedwhen there is a mechanical
delay in the brake. See digitalinput signal External brake acknowledge.

CL: startup torque “StartUp torque!
0 = Not Used
1 = Torque Memory
Torque memory uses the torque that was used by the speed controller last time the
drive was in running state. Normally, this is the torque generated when the zero speed
time at stop has expired and the drive has stopped modulation or started the flux off
delay function.
2 = Torque Reference The normal torque reference chain is used (expect TorqueStep)
for the start-up torque level. This can be used when the external system knows the
load on the shaft when brake is released.
3 = Torque Forwad/Reverse
Drive uses torque values defined by the start-up torque
forward and reverse.
P1.15.12.2
633
Start-up torque, forward ID“StartupTorq FWD”
Sets the start-up torque for forward direction if selected with pararameter
Startup Torque.
P1.15.12.3
634
Start-up torque, reverse “StartupTorq REV”
Sets the start-up torque for reverse direction if selected with pararameter
Startup Torque.
P1.15.12.4
1371
Start-up torque time “StartupTorq time”
This parameter defines for how long the start-up torque will be used instead of the
speed controller output. If thetime is set to –1 the drive will automatically start to use
thespeed controller when speed change is read from encoder.When the setting is >0
the drive will use this defined torqueeven if speed changes are read from encoder.
Settings the start-up torque time is set to –1 means thatthe
start-up torque is removed when the drive noticesencoder
movement. Setting the time greater than 0 willdenote the
actual time for how long the start-up torqueis applied to the
motor even if the motor shaft is alreadyrotating thus making
the motor accelerate without controluntil time has expired.
