Chapter 1 Detail Drive Configuration and Operation
To configure the drive for 3-wire control with a current limit 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] = 9 “Current Limit Stop”
2. Set parameter 840 [DigIn3 Sel] = 2 “Start”
To control from a communication network:
1. To perform a current limit stop, toggle bit 8 “CurrLim 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.
Note: In 3-wire mode, all stops commanded from pressing the HIM stop
button are ramp stops.
Configuring the Start and Stop for 2-Wire Control (Maintained Start
and Stop)
To configure the drive for 2-wire control with a ramp stop:
For parameter 153 [Control Options], set bits 3 “2WCurrLimStp”, 8
“3WireControl”, and 9 “2W CoastStop” to off (0).
To control from digital inputs:
• Set parameter 839 [DigIn2 Sel] = 3 “Run”
To control from a communication network:
• To perform a ramp stop, toggle bit 1 “Start” in the logic command word on
and then off.
To control from the HIM:
• Hold down the start button to run and release the start button to perform
a ramp stop.
