Completed position number (PM1 to PM32)
These signals can be used to check the completed position number when the PEND signal turns ON.
The signals are output as a binary code.
Immediately after the power is input, all of the PM1 to PM32 signals are OFF.
(Only with an expanded controller the binary code consists of six bits from PM1 to PM32. The binary code
for all other controller types consists of four bits from PM1 to PM8.)
All of PM1 to PM32 are OFF also when the actuator is moving.
(Note)
All of PM1 to PM32 will turn OFF when the servo is turned OFF or an emergency stop is
actuated. They will return to the ON status when the servo is turned ON again, provided that the
current position is inside the in-position range with respect to the target position. If the current
position is outside the range, the signals will remain OFF.
When the power is input, the PEND signal will turn ON. Since PM1 to PM32 are all OFF, this
condition is the same as one achieved after positioning to position “0” is completed.
Check the position of position 0 after the movement command has completed.
If an alarm is present, the corresponding alarm code (abbreviated form) consisting of four bits from PM1 to
PM8 will be output.
The meanings of these signals vary between the normal condition and the alarm condition, so be careful
not to use them wrongly in the sequence.
Zone (ZONE1, ZONE2)
Use a ZONE signal as a limit switch at an intermediate point or as a simple ruler.
The ZONE1 signal will turn ON when the current position is inside the range specified by user parameter
Nos. 1 and 2, and turn OFF if the current position is outside this range.
(If the 2 zone output signals pattern is selected, the ZONE2 signal will turn ON/OFF in the same manner
with respect to the range specified by user parameter Nos. 23 and 24.)
(Note)
The ZONE signals are enabled after the coordinate system is established following a completion
of home return. They will not be output simply by turning on the power.
As long as home return has completed, the ZONE signals remain enabled while the servo is
OFF or during an emergency stop.
Current operation mode (MODES)
This signal is enabled when the teaching pattern is selected.
The MODES signal will turn ON when the teaching mode is enabled upon selection of the teaching mode
via the operation mode input signal (MODE signal ON).
Thereafter, the MODES signal will remain ON until the MODE signal turns OFF.
Configure the system in such a way that the PLC will start teaching operation after confirming that the
MODES signal has turned ON.
Write completion (WEND)
This signal is enabled only when the teaching pattern is selected.
The WEND signal is OFF immediately after the controller has switched to the teaching mode. It will turn
ON when the writing of position data in response to the current-position write signal is completed.
When the current-position write signal turns OFF, this signal will also turn OFF.
Configure the system in such a way that the PLC will acknowledge completion of writing when the WEND
signal turns OFF.
