3.2.68.6
Additional setpoint
l
An additional setpoint (e. g. a correction signal) can be linked with the main setpoint via the
input NSET−NADD.
l
The input signal can be inverted via the input NSET−NADD−INV before affecting the ramp
function generator. The ramp function generator has a linear characteristic and an acceleration
time and deceleration time each.
l
With NSET−LOAD = HIGH the ramp function generator is set to zero and kept there without
considering the T
i
times.The same applies when the controller is inhibited.
Tip!
Do not link the main setpoint with negative additional setpoints when C0190 = 3 or C0190 =4!
Otherwise the drive may change its direction of rotation!
The drive behaviour depends on the times set for the main setpoint and additional setpoint at the
ramp function generator.
