5 Parameter Setting and Functions
5.4.1 Setting Reference Units
(3) Setting Speeds in Reference Units
Calculate the positioning speed.
<Example>
Reference unit: 0.01 mm
Desired positioning speed: 15 m/min
15000 mm/min
0.01 mm
Thus, the positioning speed setting is 1500 [1000 reference units/min].
Specify the positioning speed and registration speed in the program table in SPD and RSPD.
Specify the JOG speed in the JOG speed table in JSPD.
Specify the positioning speed and registration speed with the SPD and RSPD serial commands. The SPD and
RSPD commands can be omitted; in this case, the setting in the following parameter will be used.
PnB27
(4) Setting Reference Unit Acceleration/Deceleration, and Average Movement Time of
Position References
Calculate the acceleration/deceleration.
<Example>
Reference unit: 0.01 mm
Acceleration time from 0 m/min to 15 m/min: 100 ms
15000 mm/min
0.01 mm
1500000 reference units/min
Thus, the acceleration setting is 15 [1000 (reference units/min)/ms].
