Flag signal: M1063

Explanation

1. S

: torque command (display in signed decimal with one decimal place)

speed limit

2. This command can control torque command and speed limit. Special register

control is shown as following:

M1040: controls Servo On(On)/ Servo Off(Off). Torque output and speed limit

are defined by the setting of TORQ command when TORQ command is set

when Servo is ON.

Example

1. M1040: control Servo On(On)/ Servo Off(Off). M1063: target torque attained.

D1060: control mode setting. D1053: actual torque.

2. When M0=Off, setting torque command of the AC motor drive to K+300(+30.0%)

and speed limit to 3000(30Hz).

3. When M0=On, setting torque command of AC motor drive to K-300(-30.0%) and

speed limit to 3000(30Hz)。

4. When M10=On, AC motor drive begins to execute torque command.

5. When target torque is attained, M1063 will switch ON and flag signal will be

blinking.
