9-2 Timing Chart
9-2-1 Servo-on signal accept timing on power-up
• The above chart shows the timing from AC power-ON to command input.
• Input the servo-On command, position/velocity/torque commands according to the above timing chart.
*1. It is shown that an instruction input receptionist is not ready in this section.
Please input instructions after the completion of preparation.
*2. The servo ready is turned on when all the following conditions are satisfied: “Initialization of microcomputer is
completed”, “Main power supply is established”, “No alarm is issued”, and “Synchronization (phase matching)
between EtherCAT communication and servo is completed and EtherCAT communication is established”.
*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 Pr 6.18 Wait time after power-up.
*4. A brake release output (BRK-OFF) is output by a release request from the EtherCAT communication (set brake
of 60FEh).
