P042 [Initial Braking Pressure] – New Parameter
This is the new parameter, which affects the DC braking performance.
Values Default 1200
Min/Max: 80/2000
Display: 1
Parameters Settings
The following parameters may need to be adjusted for the quick stop application.
P037 [Stop Mode]
Set this parameter to one of the DC braking modes (2, 3, 6, or 7).
Mode 3 is probably the preferred mode, but mode 2 may provide slightly better
performance if there is mechanical inertial or and mechanical backlash. Mode 3
applies braking until the drive stops then releases the brake. If there is still some
external mechanical inertia when the brake is released the drive (system) may coast
for a short distance. Mode 2 applies the brake for the full period of time specified in
parameter 80 acting as a holding brake even after the motor comes to rest. Mode 6
is the same as Mode 2 and Mode 7 is the same as Mode 3 except that Mode 6 and 7
do not permit a simple stop to clear faults if they occur.
