12.2.1 Motor Speed

For program table operation, the positioning speed is registered in SPD and the registration
speed is registered in RSPD. For jog speed table operation, the jog speed is registered in
JSPD.
For operation with serial command communications, the positioning speed is specified with the
SPD command and the registration speed is specified with the RSPD command. You can omit
the SPD command or PSPD command. If you do, the setting of the following PnB27 parameter
(Positioning/Registration Speed) is used.
The speed is set in units of 1,000 reference units/min.

If you set PnB54 to 1 (Enable Expansion Mode), the range will be 1 to 199,999,999. Refer to the following section
for details.

12.2.2 Acceleration Rate and Deceleration Rate

For program table operation, the acceleration rate is set in ACC and the deceleration rate is set
in DEC.
For jog speed table operation or operation with serial communications, the settings of the fol-
lowing PnB29 parameter (Acceleration Rate) and PnB2B parameter (Deceleration Rate) are
used.
In serial command communications, the ACC command sets PnB29 (Acceleration Rate) and
the DEC command sets PnB2B (Deceleration Rate).
The acceleration and deceleration rates are set in units of 1,000 reference units/min/ms.

Positioning/Registration Speed
Setting Range
1 to 99,999,999*
The following calculation applies if the reference unit is 0.01 mm and the positioning
Example
speed is 15 m/min.
15,000 mm/min
0.01 mm
Thus, the positioning speed setting is 1,500 [1,000 reference units/min].
