2.4.47.3
Setpoint inversion
The output signal of the JOG function is led via an inverter.
The sign of the setpoint is inverted, when the input NSET−N−INV = HIGH.
2.4.47.4
Ramp function generator for the main setpoint
The setpoint is then led via a ramp function generator with a linear characteristic. The ramp function
generator converts setpoint jumps at the input into a ramp.

Acceleration and deceleration times of the ramp function generator
l
The acceleration and deceleration ramps can be separately selected.
– Via the inputs NSET−TI*x 16 you can activate different acceleration and deceleration times
(see JOG setpoints, table and function. The decoding is made according to the signal plan).
– The T
i
times can only be activated in pairs.
l
When the controller inhibit (CINH) is set, the ramp function generator accepts the value at the
input NSET−CINH−VAL and passes it on to the following 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 signal.
l
NSET−RFG−0 = HIGH
– The ramp function generator decelerates to zero along its deceleration ramp.
l
It is also possible to load the ramp function generator in advance with a value. For this, the
input NSET−LOAD must be set = HIGH. As long as this input is set, the value at the input
NSET−SET is accepted by the ramp function generator and provided at the output.
