Timing Chart
<Cautions>
• The above chart shows the timing from AC power-ON to command input.
• Activate the external command input according to the above timing chart.
*1. In this term Servo-ON input (SRV-ON) turns ON as a hard ware, but operation command can not be
received.
*2. S-RDY output will turn on when both conditions are met, initialization of micro computer has been com-
pleted and the main power has been turned on.
*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 external scale input, so as to decide their logic until this term.
