Accelerating time zero for controller
enable (from SW 3.1)
– x – STW1.13
The ramp–function generator (RFG) can be enabled/disabled as a function of the controller enable via
this input signal.
1 signal Operating case: Controller enabled
––> the drive ramp–function generator is off
––> the ”zero ramp–up time” is controlled
––> a higher–level control can assume the ramp–function generator
function
Error situation: Controller not enabled
––> drive ramp–function generator is on
––> the drive brakes via P1257:8 (ramp–fct. generator ramp–down time)
0 signal Ramp–function generator on
Application:
The following is valid when the signal is set:
If the controller is enabled, a higher–level control can assume the ramp–function generator function. If the
controller is not enabled, the drive ramp–function generator is again effective.
Note:
Refer to the ”zero ramp–up time” input signal
Master sign–of–life
(from SW 3.1)
– x x STW2.12
STW2.13
STW2.14
STW2.15
For the ”Motion Control with PROFIBUS–DP” function, these control signals are used as sign–of–life
(4–bit counter).
The sign–of–life counter is incremented from 1 to 15 and then starts again with the value 1.
Note:
The ”Motion Control with PROFIBUS–DP” function is described in Chapter 5.8.
Activate function generator (edge) (from SW 8.1) – x – STW1.8
When the function generator or the measuring function is appropriately parameterized, a synchronous
start of the function generator or the measuring function is activated – e.g. for mechanically coupled axes
(gantry axis group).
0/1 signal Function generator or measuring function is activated
1/0 signal Function generator or measuring function is de–activated
Note:
The function generator is described in Chapter 7.4.1.
