7.3
Special Functions
7.3.1
Emergency Stop (/STOP)
The Emergency Stop function can be used as an additional protective function. Emergency
Stop can be triggered from a variety of difference control locations:
The ramp can be entered in units min
-1
s
-1
at which the motor is to be braked down to Speed=0,
using the Stop Ramp parameter STOPR (_CONF). With the setting STOPR= 0 (factory setting)
the motor is braked at the set torque limit (TCMMX in area _TCON) as quickly as possible
(Emergency Stop without ramp).
Control of the drive remains switched on and the motor is held speed controlled in this position.
The Emergency Stop can be activated from any control mode.
Note
If torque limiting (SCALE Function) is activated, it also takes effect in the case of an Emergency
Stop.
Resetting the Emergency Stop:
Emergency Stop condition remains until the /STOP-Signal and the Start signal have both been
reset.
Warning!
The ENPO signal must not be discontinued during the Emergency Stop condition or the motor
would be isolated from its control. In that case, the Servocontroller would lose control of the
motor and the motor would coast on uncontrolled.
7.3.2
Auto Start
In many applications it may be necessary to enable control automatically after switching on
mains power. In such cases the parameter AUTO should be set to the value "ON" in the area
(_CONF). After mains power is switched on (even after a short power failure) control is
automatically switched on if the Start signal is present
Note:
1. The Start Signal may be applied continuously if a fixed input FIF0 or FIF1
(_CONF) =START. The input IS00 can then have another function assigned to it.
2. There is no Start signal after a mains power supply failure when controlling from the CTRL-
Menu.
