• 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 (SRV-ON) turns ON as a hard ware, but operation com-
mand can not be received.
*2. S-RDY output will turn on when both conditions are met, initialization of micro com-
puter has been completed 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 (POT, NOT) or external scale
input, so as to decide their logic until this term.
The lapse time can be changed with Pr6.18 Wait time after power-up.
*4. Servo ON status output (SRV-ST) is a signal indicating that it has received the Servo-
On input; please note that it is not an indication showing command input is possible.
