Function
h3Stioning
I A single, specified positioning is executed -+ completed, then operation stops.
Continuous
positioning
A single, epecified positioning is executed+ completed, ffren operation pausea, after which
positioning for the neti number is exacutad continuously. This action is repeated until a positioning
i with the [positioning complete] operation pattern is executed.
Continuous
locus
positioning
A single, specified positioning ia executed + completed, and without pausing positioning for the
nexi number is executed continuously. This action is reDeated until a Dositioninowith the
I [positioningcomplete] operation pattern is executed.

Block positioning
I Two axes are controlled simultaneously, and positioning toward the specified address is executed
I alonaa linearor circularlocus.
The next poelioning is executed by treating as one block all positioning data up to the one with the
[positioningcomplete] operation pattern.
.
Postiioning for specified multiple blocks is executed continuously.
●
Positioning for a desired block is repeated until the condition spacified by the usar is satisfied.
.
Positioning for a dasired block is repeatad for the number of times specified by the user.
Speed control
;After acceleration to the specified speed, operation is performed at the same speed until a stop
1command is input. (Travel increment and address are not specified.)
SpeerYposition
switchcontrol
; Initially, operation is performed at the same specified speed (same status as during speed control),
and with input of a epeed$msittin switch stop signal, positioning for the specified travel increment is
executed + completed and operation atops.
I
Aanual pulse-genarator operation function
Pulses ara input from the manual pulse ganemtor, and positioning is execut~
lK)t3operation function
A JOG operation command is input fmm the PC or peripheral device, and while the command
remains on, apeed control is executed in the specified direction at the specified speed.

manually.
Wfih a home position return command from the PC or peripheral device, positioning to the
mechanical home position is performed, and when positioning is complete the present address
~(present feed value, machine feed value) is corrected to tha homa position address.
(There is a home oosition return retrv function.)
Adjusts the travel increment per pulse according to the mechantil
system.
During positioning operation, JOG operation, manual pulse-generator operation or home position
return operation, extra feed PUIWS are output for the aet backlash compensation amount to adjust
the travel increment for the mechanical system.
When an error (mechanical system error) between the specified travel increment and actual travel
I increment occurs, the Puise output for the error pofion is corrected by adjusting the eleotmnic gear
setting.
Calls the number referred to as M-cede which ia set for each positioning dat@ confirms the
positioning data currently executed and commands auxiliary operations (clamp, drill rotation, tool
replacement, etc.).
Acceleretionkfeceleration control function
I
I and JOG otreretionor at home oosition return stafl and finish, is executed as the specified
trapezoidal acceleretiotidecele”mtion or S-curve accelerationldeceleretion.
Software limit function
I Any positioning command exceeding the high or low limit of the specified machina movement range
is not executed.
Torque mntrol function
The torque generated by the eervo motor is limited so that is doee not exceed the specified torque
control value. The torque is controlled with the changed limit value when the torque control value is
changed during positioning.
Present-value change function
Tha present fead value ia changed to the specified value.

Teachingfunction
When the unit is in dagree, positioning is performed in the direction closer to the specified address.
Receives inkmration of the abeoluto peeirion from the aawo amplifier, and GhaIIgOS the present value.
This is a manualoperation via JOG operation and manual pulse-generator operation, by which tha
aligned positioning addreas is aet agein as the positioning data for the specified number.
1Step function
Skip function
Stops operation after avery positioning action in order to confirm the positioning action.
Stops the fmsitioning currently executed and axecutes the naxf positioning.
*1: Valid only when MR-H or MR-J2 is used for the servo amplifier.
