M1040: controls Servo On(On)/ Servo Off(Off). M1055: searching origin point.

M1048: operate to the new position point. In the condition D1060 = 1 (control

mode is set to position mode), M1040=1 (Servo ON), and DPOS command is

given; when M1048 is set from OFF to ON the AC motor drive will operate till the

new position point.

Example

1. M1040: controls Servo On(On)/ Servo Off(Off). M1064: target position attained.

D1060: control mode setting. D1051(L) and D1052(H): actual position point.

2. When X0=On, setting M1040 to ON (Servo On).

3. When X1=On, setting DPOS position command to +300000. It will delay for 1

second then set M1048 to ON (operate to the new position). Please observe if the

D1051 value changes. When position is attained, M1064 will set to ON and Y0

will output an ON signal.
