2.12.4 Quick Stop

66
The fast stop indicates that the motor is stopped in automatic mode via pin 4
of the sensor inputs I1 and I2 for RAMO5 and RASP5.
The input signals are directly processed in RAMO5 as per RASP5. PLC and
bus cycle times have no influence on the switch-off time.

a Internal response time
b Signal O1 from PLC through AS-Interface
c Internal signal to motor output as response to the rising edge of the sensor at pin 4 (Stop) and to
the subsequently rising edge of PLC O1 (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 pin 4 input signal (rising edge) switches the motor output off. When the
PLC output (AS-I signal Q1) is reset (falling edge), the motor output can be
switched back on. Whether or not the input signal is still being applied when
the PLC output is reset or switched back on is irrelevant ￫ Figure 31.
The FWD or REV LED flashes when the motor output is switched off by
means of quick stop and the PLC continues to set the corresponding rota-
tional direction bit.
During operation, the FWD or REV LED will light up as applicable if the PLC
has set the corresponding operating direction bit.
