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.
