Detail Drive Configuration and Operation Chapter 1
Configuring the Start and Stop for 3-Wire Control (Momentary Start
and Stop)
To configure the drive for 3-wire control with a ramp stop:
For parameter 153 [Control Options], set bit 8 “3WireControl” to on (1) and set
bits 3 “2WCurrLimStp” and 9 “2W CoastStop” to off (0).
To control from digital inputs:
1. Set parameter 839 [DigIn2 Sel] = 1 “Normal Stop” or = 5 “Stop - CF”.
“Stop - CF” indicates that the same digital input is used as a stop and a
clear fault.
2. Set parameter 840 [DigIn3 Sel] = 2 “Start”.
To control from a communication network:
1. To perform a ramp stop, toggle bit 0 “Normal Stop” in the logic command
word on and then off.
2. To perform a start, toggle bit 1 “Start” in the logic command word on and
then off.
To configure the drive for 3-wire control with a coast stop:
For parameter 153 [Control Options], set bit 8 “3WireControl” to on (1) and set
bits 3 “2WCurrLimStp” and 9 “2W CoastStop” to off (0).
To control from digital inputs:
1. Set parameter 839 [DigIn2 Sel] = 10 “Coast Stop”
2. Set parameter 840 [DigIn3 Sel] = 2 “Start”
To control from a communication network:
1. To perform a coast stop, toggle bit 9 “Coast Stop” in the logic command
word on and then off.
2. To perform a start, toggle bit 1 “Start” in the logic command word on and
then off.
