Invert main setpoint
The main setpoint can be inverted via terminals E1 and E2 (i.e. the sign of the input value is changed.
Mandatory:
E1 E2 Main setp oint
0 0 Drive performs QSP (quick stop)
1 0 Main setpoint not inverted
0 1 Main setpoint inverted
1 1 Drive maintains its previous state
Acceleration and deceleration times for the main setpoint channel
The main setpoint is led via a ramp generator. Thus, jumps can be converted into a ramp.
The acceleration time and deceleration time refer to a speed change from 0 to n
max
(0% to 100%).
The calculation of the times T
ir
(C0012) and T
if
(C0013) to be set is described in the NSET function
block description.
Additional acceleration and deceleration times
For the ramp generator of the main setpoint (NSET-N/JOG setpoint), you can call additional
acceleration and deceleration times from the memory via the inputs NSET-TI*x, for instance, to
change the acceleration time of the drive as from a defined speed. For this, these inputs must be
assigned to a signal source. A maximum of 15 additional acceleration and deceleration times can be
programmed.
S-shaped acceleration characteristic
Under C0134, you can select two different characteristics for the ramp generator of the main
setpoint:
z linear characteristic for all accelerations requiring a constant acceleration
z S-shaped characteristic for all accelerations requiring a jerk-free acceleration

Additional setpoint
An analog additional setpoint (bipolar) can be added via the input X6/3,4 (or another signal source).
The additional setpoint (display in C0049)is led to the NSET function block via an analog switch. The
additional setpoint is led via an inversion. Thisinversion is deactivated. The additionalsetpoint is then
passed to a ramp generator (acceleration and deceleration times via C0220/C0221), and finally
added to the main setpoint in the arithmetic block. The additional setpoint can be used e.g. as a
correction signal for grinding machines (for the control of a constant circumferential speed when the
diameter of the grinding wheel is reduced).
If you want to use the additional setpoint, set code C0190 to the desired arithmetic operation. In the
default setting, code C0190 is set to 0. This means that the additional setpoint is switched off.
