4.5 Example of Setting Motion Parameters for the Machine
4-105
( 5 ) Speed Reference
There are two methods of setting the speed reference for the feed speed or other speeds. One method
involves using reference units and the other method involves setting the percentage (%) of the rated
speed. The following table shows the parameters relating to speed references.
Parameter Type
Parameter No.
(Register No.)
Name Description
Default
Value
Motion Fixed
Parameters
No. 5
Number of
Decimal Places
Set the number of digits below the decimal point in the input
reference unit. The minimum reference unit is determined by this
parameter and the Command Unit (fixed parameter 4).
Example:
Command Unit = mm, Number of Decimal Places = 3
1 reference unit = 0.001 mm
3
No. 34 Rated Speed
Set the number of rotations when the motor is rotated at the rated
speed (100% speed). Confirm the motor specifications before
setting this parameter.
3000
No. 36
Encoder
Resolution
Set the number of pulses (the value after multiplication) per motor
rotation.
Example:
For a 16-bit encoder, set 2
16 = 65536.
65536
Motion Setting
Parameters
OW††03,
bits 0 to 3
Speed Units
Set the unit for reference speeds.
0: Reference unit/s
1: 10
n reference units/min (n: Number of Decimal Places)
2: 0.01%
3: 0.0001%
1
OL††10 Speed Reference
Set the feed speed. The unit for this parameter is set in
OW††03, bits 0 to 3.
When the Number of Decimal Places is set to 3, units are as
follows for the setting of the Command Unit:
• Speed Unit Set to 0: Reference units/s
Pulse unit: 1 = 1 pulse/s
mm unit: 1 = 0.001 mm/s
Deg unit: 1 = 0.001 deg/s
Inch unit: 1 = 0.001 inch/s
• Speed Unit Set to 1: 10 n reference units/min
Pulse unit: 1 = 1,000 pulses/min
mm unit: 1 = 1 mm/min
Deg unit: 1 = 1 deg/min
Inch unit: 1 = 1 inch/min
• Speed Unit Set to 2: 0.01%
Set as a percentage of the rated speed (1 = 0.01%) unrelated to
the reference unit setting.
3000
OW††18 Speed Override
This parameter allows the positioning speed to be changed
without changing the Speed Reference setting. Set the speed as a
percentage of the Speed Reference setting.
Setting unit: 1 = 0.01%
