•The above chart shows the timing from AC power-ON to command input.

•Activate the external command input according to the above timing chart.

Caution

*1. In this term Servo-ON input (CN X5 SRV-ON:pin23) turns ON as a hard ware, but operation command can not be received.

*2. Servo alarm output (CN X5 ALM:pin15) turns ON when the microcomputer's initialization is completed, and the condition of no error is occurring. Servo-ON input turns ON after Servo alarm turns ON and the main power supply is activated sufficiently.

*3. After Internal control power supply , protective functions are active from approx. 1.5 sec after the start of initializing microcomputer. Please set the signals, especially for protective function, for example over-travel inhibit input (CWL,CCWL) or emergency stop input (EMG-STP), so as to de- cide their logic until this term.
