12-1 Position Control (including homing function)

Suppose that the machine will move to limit switch (CCWL), L.S.1 when motor is in forward rotation (from

motor shaft view) and the machine will move to limit switch (CWL), L.S.2 when motor is in reverse rotation, if

limit switch is set, L.S.1 as “Home”, the machine will be positioned between P1 and P2 according to working

procedure.

PLC

L.S.1

P2 L.S.2

Parameters Setting

 P1-01=1 (Position control (Pr) mode setting)

 P1-47=100 (Activate forward homing)

 P2-15=022 (Reverse inhibit limit (CWL). Then, connect contact “b” of L.S.1 to DI6)

 P2-16=023 (Forward inhibit limit (CCWL). Then, connect contact "b” of L.S.2 to DI7)

 P2-10=101 (Servo On (SON), default: DI1)

 P2-11=108 (Command triggered (CTRG), default: DI2)

 P2-12=111 (Position command selection (POS0), default: DI3)

 P1-33=0 (Absolute position command)

 Set P1-15, P1-16 as position P1 (Internal position command 1)

 Set P1-17, P1-18 as position P2 (Internal position command 2)

 P2-18=101 (Servo ready (SRDY), default: DO1)

 P2-21=105 (Positioning completed (TPOS), default: DO4)

 P2-20=109 (Home completed (HOME), default: DO3)

 P1-50=0, P1-51=0 (Homing offset rotation / pulse number)

 Other relevant parameters: P1-34, P1-35, P1-36 (Acceleration/Deceleration time setting); P1-48, P1-49

(Speed setting of high/low speed Homing)

Operation

 Re-start the power to be ON again.

 After Servo ready is completed, activate the drive to be Servo ON. Then, the system will automatically

complete home operation.
