Solution
The drive is enabled and stopped via the inputs for the direction of rotation. The function of the digital
inputs remains unchanged. The internal signal processing for quick stop (QSP) has been adapted
accordingly.

Fig. 3−2 Changes made in configuration 1000 for accelerating and decelerating in a constant time
 Setpoint
‚ Setpoint for input MCTRL−N−SET
Parameter setting
1. Remove the connection between the output R/LQ−QSP and the input MCTRL−QSP of the FB
MCTRL.
2. Set MCTRL−QSP to FIXED0 (C0900 = 1000).
3. Connect the output R/L/Q−QSP with the input NSET−RFG−0 (C0789 =10250).
4. Set C0104 = 1
– The drive accelerates to the setpoint at X6/1,2 or decelerates to zero speed in a constant
time.
5. Select the acceleration time (T
ir
) under C0012 and the deceleration time (T
if
) under C0013.
Tip!
If you want to use different acceleration and deceleration times, select the desired Ti time before or
at the same time with the changeover of the setpoint at NSET−RFG−0.
