GEAR.TORQ TIME (2316) is the time period after the direction
change when GEAR.START TORQ torque limit is used. Scale: 1 =
1 ms.
GEAR.TORQ RAMP (2317) defines the rate of change for the
torque limit when GEAR.TORQ TIME has elapsed. GEAR.TORQ
RAMP is given as the maximum change of torque limit in 3.3 ms
(50Hz). Scale: 4000 = nominal torque of motor
