●Fieldbus Message Output Timing
● Basic Control Signals: Slave Spindle
● Delay Time from Input of START Signal to Unit Startup
･ Startup processing time of MASTER spindle for PC communication and I/O (PLC) control: Approx. 170 to
180msec
･ Startup processing time of SLAVE spindle for PC communication and I/O (PLC) control: 3msec (per axis)
Example: Processing time for a 10-axis system = (170 to 180msec) + 3msec × 10 axes
The respective SLAVE spindle are thus started up 200 to 210msec after the MASTER spindle is started
up.
