The following steps show how to get a rotating drive to a “safe stop”:<br />
1. Before activating the “safe stop” (i.e. driver supply relay “OFF” and output stage enabling “OFF”;<br />
both shut-down paths inhibit the PWM signals) the drive should be stopped by deactivating the<br />
controller enabling. Depending on the application, the brake ramp (t9-t8) can be set via<br />
ServoCommander (“Quick stop deceleration”).<br />
Activation of the “safe stop” function during operation will cause the drive to run down. If<br />
the drive has a holding brake it will be activated. It is therefore very important to make<br />
sure that the motor brake can actually stop the motion of the drive.<br />
2. After 0 speed has been reached, the drive will be controlled to this set value for a parameterizable<br />
drop-out delay time (t10-t9). This parameterizable time is the deceleration, at which the holding<br />
brake of the motor is applied. This time depends on the holding brake and must be set by the<br />
user. For applications without holding brake this time can be set to 0.<br />
3. After this time has run out, the internal output stage enabling will be switched off by the µP (t10).<br />
The holding brake will definitely be activated as soon as the “brake ramp time + set drop-out delay<br />
time” has run out, even if it the drive has not yet been able to stop!<br />
4. As of t10 the “safe stop” can be activated (simultaneous deactivation of triggering of driver<br />
supply relay and output stage enabling). The time (t11-t10) depends on the application and<br />
must be set by the user.<br />
5. With the withdrawal of the trigger signal for the relay that switches off the driver supply<br />
(t11) the capacitors in this voltage branch will be discharged. Approx. 80ms (t12-t11) after<br />
the withdrawal of the trigger signal for the relay that switches off the driver supply, the<br />
feedback contact ([X3], pins 5 and 6) will be closed.<br />
6. At the time t13 the letter “H” will be shown on the 7-segment display of the servo controller<br />
for the visualization of the “safe stop” function. This will happen no later than 30ms after<br />
the closing of the floating feedback contact (t13-12).<br />
