RAMP_OUT_
ZERO (ABB DRV
FULL)
1 Enter RAMP FUNCTION GENERATOR: OUTPUT
ENABLED.
0 Force Ramp function generator output to zero.
Drive ramps to stop (current and DC voltage limits in force).
5 RAMP_HOLD 1 Enable ramp function.
Enter RAMP FUNCTION GENERATOR: ACCELERATOR
ENABLED.
0 Halt ramping (Ramp function generator output held).
6RAMP_IN_
ZERO
1 Normal operation. Enter OPERATING.
0 Force Ramp function generator input to zero.
