7.7 Safety stop functions

As shown above, all these safety and start-up features are programmable and a digital input pin
or logical behaviour of this pin (high-, low-active) can be selected.
The following safety functions bring about controlled stopping of the machine, pre-defined by the
deceleration times selected within the spindle characteristics,
•
Safety stop by spindle overtemperature, if this function is activated and it's delay-time exceeded
In form 'Spindle' this function can be enabled with the check button Temp. sense and in form
'delays' the delay time can be specified.
•
Safety stop by converter over-temperature and delay-time exceeded, specified in the form
'delays' (accessed by delays button)
•
Safety stop by overload and time delay exceeded (determined by maximum current and voltage
in the spindle diagram and the form 'delays', accessed by delays button)
•
Immediate safety stop by over-current of the converter.
•
Safety stop by emergency stop through digital input shutdown in form 'digital inputs'
The following stopping methods shut off the power stage and the spindle will slow down only
though its own load. This process can take up to ten minutes until the spindle has fully stopped:
•
Safety stop via short-circuit protection on digital input PDP Interrupt determined by internal
converter current limit.
•
Safety stop by digital input PWR stage off in the form 'digital inputs'.
After an error flag has occurred, it must be cleared by a Start/Stop sequence or a digital error
reset with a digital input (in form 'digital inputs' Error reset). 4 seconds after error reset, the
device is ready for operation again.
