7.6.52.3 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 a HIGH signal.
Ramp generator for the main setpoint
The setpoint is then led via a ramp generator with linear characterisitc. Setpoint step-changes are
thus transformed into a ramp.

Fig. 7-127 Acceleration and deceleration times of the ramp generator
l
The ramps can be adjusted separately for acceleration and deceleration.
– 16 acceleration and deceleration times can be switched active via the inputs NSET-TI*x (for
table and function see JOG setpoints; they are decoded according to the signal graphic).
–TheT
i
times can only be activated in pairs.
l The controller inhibit (CINH)is set, the ramp generator accepts the value which was applied at
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 generator is stopped. Changes at the input of the ramp generator have no effect
on the output.
l NSET-RFG-0 = HIGH
– The ramp generator decelerates to zero along its deceleration ramp.
l It is also possible to load the ramp 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 the input NSET-SET
is accepted by the ramp generator and provided at the output.
