5-10.Slow Stop Function
The pulse output can be put into a slow stop by the SLOW STOP command.
After the pulse output is stopped in the above way, SSEND becomes 1.
5-11.Fast Stop Function
When you use emergency stop in response to system failure, also turn off power of the
WARNING
drive system. If an error has occurred to the controller or wiring system, the Fast Stop
may not work. This may lead to a serious accident. For details, refer to Chapter 19.
The pulse output can be put into an fast stop by the FSSTOP command or FSSTOP signal.
After the pulse output is stopped in the above way, FSEND becomes 1.
FSSTOP signal stops four axes, X, Y, Z and A immediately.
5-12.LIMIT Stop Function
When you use emergency stop in response to system failure, also turn off power of the
WARNING
drive system. If an error has occurred to the controller or wiring system, LIMIT Stop
may not work. This may lead to a serious accident. For details, refer to Chapter 19.
If any error has occurred to the system or your setting is incorrect, the machine or
CAUTION
workpiece damage and personal injury may occur. To prevent such an accident, be sure
to use the LIMIT Stop function for the equipment except on the rotation system.
When you use the LIMIT stop as slow stop, there may be a collision with the limit
CAUTION
position of the mechanical device before stop. This may lead to machine or workpiece
damage. Note that the stop point will be changed if RATE, HSPD, etc. are changed.
The pulse output can be stopped by the CWLM signal when the pulse output is in the +(CW)direction or by
the CCWLM signal when the same output is in the -(CCW)direction. After the pulse output is stopped in the
above way, LSEND becomes 1. The LIMIT stop type can be switched between fast stop and slow stop by
the SPEC INITIALIZE1 command. "Fast stop" is selected at POWER ON/RESET.
5-13.Function for Servo Driver
The target motor can be switched by the SPEC INITIALIZE1 command. The target motor is a servo motor or
a stepping motor. "Stepping motor" is selected as the target motor at POWER ON/RESET.
The signals for servo motor are as follows.
DEND input signal: The deviation COUNTER END signal from the servo driver is input.
Even after the
completion of pulse output, the driving status is kept until DEND=LOW is confirmed,
and the command is not terminated with BUSY and DRIVE BIT=1.
DRST output signal: The deviation COUNTER RESET signal is output to the servo driver. If the pulse output
is put into an fast stop, the DRST signal=LOW is output for 10ms and the deviation
COUNTER of the servo driver is reset. The DRST signal=LOW can also be output
optionally for 10ms by the SERVO RESET command.
The above signals are disabled when a stepping motor is selected as the target.
In this case, DEND input and DRST output can be used as a general purpose input and general purpose output,
respectively.
For their usage, refer to the User's Manual [Applied Functions Part].
5-14.Current Position Reading Function
The current position can read by the ADDRESS READ command.
The guaranteed data range is a pulse area of +8,388,607 to -8,388,607. The current position is reset to
0 at POWER ON/RESET and can also be set to an optional value by the ADDRESS INITIALIZE command.
