Quick Stop - Eaton Rapid Link 5 Manual

2.12.4 Quick stop

A Quick stop describes when the motor is stopped in Auto mode via pin 4 of
the sensor inputs I1 and I2 in RAMO5 and RASP5 units.
The input signals are directly processed in RAMO5 as per RASP5.
PLC and bus cycle times have no influence on the switch-off time.

c Internal signal to motor output as a response to the rising edge of the sensor at pin 4 (Stop) and
to the subsequently rising edge of PLC (Start)
The type of edge control (rising/falling) for the sensor inputs is defined via
parameters.
• RAMO5: P3-06, P3-07
• RASP5: P3-06, P3-07, P3-08, P3-09
The input signal at pin 4 (rising edge) switches the motor output off.
If the start signal is reset via the PLC (falling edge), the motor output can be
switched on again.
The FWD or REV LED flashes if the motor output is switched off by a Quick
stop and the corresponding rotational direction bit is still set in the PLC.
During operation, the FWD or REV LED will light up if the corresponding
operating direction bit is set in the PLC.
Example of the Quick stop function
Vertical sorter with 360° eccentric drive:
The Quick stop function makes it possible for the drive to stop at the exact
point the limit switch is reached. Preprocessing in RAMO5 or RASP5 enables
the motor to be switched off directly. PLC and bus cycle times have no influ-
ence on the switch-off time.
