4.4 Servo ON/OFF
4.4 Servo ON/OFF
Servo ON/OFF
This function executes servo ON/OFF of the servo amplifiers connected to the Motion CPU. By establishing the servo ON
status with the servo ON command, servo motor operation is enabled. The following two signals can be used to execute servo
ON/OFF.
• [Rq.1123] All axes servo ON command (R: M30042/Q: M2042) (Common on all axes)
• [Rq.1155] Servo OFF command (R: M34495+32n/Q: M3215+20n) (For each axis)
A list of the "[Rq.1123] All axes servo ON command (R: M30042/Q: M2042)" and "[Rq.1155] Servo OFF command (R:
M34495+32n/Q: M3215+20n)" is given below.
: Servo ON (Servo operation enabled), : Servo OFF (Servo operation disabled)
• Refer the following for details of servo ON command OFF and ready ON command OFF from Motion CPU.
Servo amplifier Instruction Manual
• When the delay time of "Electromagnetic brake sequence output (PC02)" is used, execute the servo ON to
OFF by "[Rq.1155] Servo OFF command (R: M34495+32n/Q: M3215+20n)".
• If the servomotor is rotated by external force during the servo OFF status, follow up processing is
performed. (Page 109 Follow up function)
• Change between servo ON or OFF status while operation is stopped (position control mode). The servo
OFF command of during operation (during start accept flag ON) will be ignored.
• When "[Rq.1123] All axes servo ON command (R: M30042/Q: M2042)" is turned OFF ON, the servo
does not turn ON for axes for which the "[Rq.1155] Servo OFF command (R: M34495+32n/Q: M3215+20n)"
is ON.
• When the servo OFF is given to all axes, "[Rq.1123] All axes servo ON command (R: M30042/Q: M2042)" is
applied even if all axis servo ON command is turned ON to OFF with "[Rq.1155] Servo OFF command (R:
M34495+32n/Q: M3215+20n)".
• Even if the Motion CPU status is STOP, ON/OFF control for "[Rq.1123] All axes servo ON command (R:
M30042/Q: M2042)" is possible.
• "[Rq.1123] All axes servo ON command (R: M30042/Q: M2042)" is forcibly turned OFF when the forced
stop input bit device is turned ON OFF (set at [Motion CPU Common Parameter] [Basic Setting]
"Forced stop input setting").
Monitor signals
The servo ON/OFF and ready ON/OFF status can be monitored with the following signals.
■Servo ON/OFF
• [St.1075] Servo ready (R: M32415+32n/Q: M2415+20n)
• [Md.108] Servo status 1 (R: D32032+48n/Q: #8010+20n) (b1: Servo ON)
■Ready ON/OFF
• [Md.108] Servo status 1 (R: D32032+48n/Q: #8010+20n) (b0: Ready ON)
[Rq.1155] Servo OFF command (R: M34495+32n/Q: M3215+20n)
