Detailed Drive Operation Chapter 1
To configure the drive for 2-wire control with a coast stop:
Set parameter 153 [Control Options] bit 8 “3WireControl” = 0.
To control from digital inputs:
• Set one of the parameters 825…830 [Dig Inx Sel] = 7 “Run”
To control from a communication network (20-COMM module):
1. Turn on bit 1 “Start” in the logic command word to run.
2. Toggle bit 9 “CoastStop” in the logic command word on and then off to
perform a coast stop. Bit 1 “Start” in the logic command word must be
turned off and back on to run again (therefore, technically, there is no 2-
Wire control with a coast stop on a network because two bits must be
controlled).
To configure the drive for 2-wire control with a current limit stop:
Set parameter 153 [Control Options] bit 8 “3WireControl” = 0.
To control from digital inputs:
• Set one of the parameters 825…830 [Dig Inx Sel] = 7 “Run”
To control from a communication network (20-COMM module):
1. Turn on bit 1 “Start” in the logic command word to run.
2. Toggle bit 8 “CurrLimStop” in the logic command word on and then off to
perform a current limit stop. Bit 1 “Start” in the logic command word must
be turned off and back on to run again (therefore, technically, there is no 2-
Wire control with a coast stop on a network because two bits must be
controlled).
Note: In 2 wire mode (parameter 153 [Control Options] bit 8
“3WireControl” = 0), the HIM Start button is not functional.
