FX Series Positioning Controllers
Conversion from the movement quantity into the pulse quantity
1) Movement quantity
Pulse quantity
=
Movement quantity per rotation of motor (feed rate)
In the system configuration shown in Paragraph 9.1, the mechanical quantity "200 mm" can
be converted into the pulse quantity as follows.
Pulse quantity [pls] =
2)Speed
Pulse quantity =
In the system configuration shown in Paragraph 9.1, the mechanical quantity "30 cm/min" can
be converted into the pulse quantity as follows.
Pulse quantity [Hz] =
Caution
• When adopting the mechanical system of units, make sure that the set value of the parame-
ter No. 4 (maximum speed converted into pulse quantity) does not exceed "200 kHz". If it
exceeds "200 kHz", the operation speed corresponding to "200 kHz" is automatically set.
• If the operation speed is set to "100 kHz" or more in the FX
during interpolation operation is automatically set to the value corresponding to 100 kHz.
