YASKAWA HV600 Manual page 491

Note:
• The drive with the lowest Y9-21 value has the highest priority and will become the Lead Drive first. If more than one drive has the lowest
Y9-21 value, then Y9-01 [Lead Drive Selection] selects which drive becomes the lead.
• When you set Y9-21 to the same value for all drives on the MEMOBUS network, it will disable this function. If more than one drive has the
same Y9-21 value, then Y9-01 will select the next Lead Drive.
• To give First Drive (and Lead Drive) control back to the drive with highest priority level set in Y9-21, set Y9-24 [Lead Swap at Sleep Delay
Time] on the other drives with a lower priority level.
