• The above chart shows the timing of actions from the time when the control power is turned on until a com-
mand is entered.
Enter the servo-on signal and the position/velocity/torque commands according to the above chart.
*1. When the internal control power has been established, the protective functions get activated approximately
1.5 s after the start of the micro computer initialization. To design your system, keep in mind that all the
input/output signals connected to the driver should be established before the protective functions start get-
ting activated; use special care for signals that can trigger the protective functions such as positive/negative
overtravel limits and external scale input. Also, this time can be extended using Pr6.18 “Power-up wait
time”
*2. After microcomputer initializing,and no errer,the output of ALM is on.
*3.
S-RDY output is turned on only when the two conditions are met: initialization of the microcomputer has been
complete, and the main power has been established.
*4. As SRV-OFF,until initialize ending,dynamic brake action is according to Pr5.07”
Sequence at main power
OFF”,after main power establish,according to Pr5.06”SRV-OFF sequence”.
*5. After the output of SRV-READY is affirmed,please start the input of SRV-ON
。
*6. The signal of SRV-ON from on to the fact of position instruction,the waiting time please
set about 100ms at least.Because from SRV-ON to the fact of power to motor need to consume some time,It is
possibility the position command cann’t be accepted.
