The operation for stop cause during speed control mode is shown below.
Item Operation during speed control mode
The Axis stop [Y4 to Y7] turned ON.
QD77MS2 QD77MS4
The " Cd.180 Axis stop" turned ON.
QD77MS16
Stop signal of " Cd.44 External input signal operation
device
" turned ON.
The motor decelerates to speed "0" by setting value
of "
Cd.142 Deceleration time at speed control mode".
The mode is switched to position control mode
when "Zero speed" of "
Md.108 Servo status" turns
ON, and the operation stops.
The All axis servo ON [Y1] turned OFF.
" Cd.100 Servo OFF command" turned ON.
The servo OFF is not executed during speed
control mode. The command status at that time
becomes valid when the mode is switched to
position control mode.
The current value reached to software stroke limit.
The position of motor reached to hardware stroke
limit
The PLC READY [Y0] turned OFF.
The error (error code: 507, 508, 104, 105, 101) will
occur. The mode is switched to position control
mode at current position, and the operation
immediately stops. (Deceleration processing is not
executed.)
The forced stop input to QD77MS.
The emergency stop input to servo amplifier.
The servo error occurred.
The mode is switched to position control mode
when the servo OFF (Servo ON of "
Md.108 Servo
status
" turns OFF) is executed. (While the servo
amplifier is servo OFF, even if the mode is switched
to position control mode, the servomotor occurs to
the free run. (The operation stops with dynamic
brake.))
The servo amplifier's power supply turned OFF.
The motor occurs to the free run. (The operation
