3.2.45 Speed setpoint conditioning (NSET)

3−133

EDSVS9332S−EXT EN 2.0

3.2.45.3 Setpoint inversion

The output signal of the JOG function is led via an inverter.

The sign of the setpoint is inverted, if the input NSET−N−INV is triggered with HIGH signal.

Ramp function generator for the main setpoint

The setpoint is then led via a ramp function generator with linear characteristic. Setpoint

step−changes at the input are thus led into a ramp.

Fig. 3−117 Acceleration and deceleration times of the ramp function generator

The ramps can be set separately for acceleration and deceleration.

– Different acceleration and deceleration times can be activated via the inputs NSET−TI*x 16

(for table and function see JOG setpoints; the decoding must be done according to the

signal graphic).

– The T

times can only be activated in pairs.

l When the controller is inhibited (CINH) the ramp function generator accepts the value that was

applied to the input NSET−CINH−VAL and transmits it to the next function. This function has

priority over all other functions.

l NSET−RFG−STOP = HIGH

– The ramp function generator is stopped. Changes at the input of the ramp function

generator have no effect on the output.

l NSET−RFG−0 = HIGH

– The ramp function generator decelerates to zero along the deceleration ramp.

l It is also possible to load the ramp function generator online with a defined value. For this, the

input NSET−LOAD must be set to HIGH. As long as this input is set, the value at input

NSET−SET is accepted by the ramp function generator and provided the output.
