No
104 Velocity feed-forward coefficient (VFFLT)
[Size] 2-byte
[Valid data range] 0 to approximately 400
[Standard value] 0
This is a velocity feed-forward coefficient parameter. For a motor with
no load, 100 specified in the parameter corresponds a coefficient of 1
(100%).
If a load inertia is added, set the parameter to a proportionally larger
coefficient.
Example)
If the load inertia is doubled:
To set velocity feed-forward to 100%: 100 × (1 + 2) = 300
To set velocity feed-forward to 50%: 50 × (1 + 2) = 150
No
105 Numerator for the number of pulses per motor revolution (SDMR1)
[Size] 2-byte
[Valid data range] 0 to 32767
[Standard value] 10000
This parameter specifies the number of pulses per motor revolution for
a detection increment, together with parameter No. 106. To be specific,
this parameter is used as a numerator.
NOTE
To set the number of pulses per motor revolution to
a value greater than 32767, set this parameter to 0,
and specify that number in parameter No. 179. Up
to 8388607 pulses can be specified.
