7.3.12 [BFM#32] Positioning parameter selection

Select whether the positioning parameter (BFM#0 to #15) is used or the extension positioning parameter
(BFM#33 to #52) is used.
BFM No.

Point
• When the parameter is changed during the operation, the change becomes valid from the next operation.
• Set the positioning parameter to the buffer memory that corresponds to the selected positioning parameter.

7.3.13 [BFM#34, #33] Pulse rate

Set the number of pulses required to rotate the motor for one turn.
Setting is necessary when the unit system is set to "machine system unit" or "combined system unit."
When "motor system unit" is selected, the setting here will be ignored.
BFM No.

#34
Point
• If any electronic gearing is present in the servo amplifier, it is necessary to consider its effect.
The relationship between pulse rate and electronic gearing is shown below.
Pulse rate = Resolution power of encoder (positioning feedback pulses) ÷ Electronic gearing
• When the positioning parameter is used, use the pulse rate (BFM#0).

7.3.14 [BFM#36, #35] Feed rate

Set the travel distance of the machine for one turn of the motor.
Setting is necessary when the unit system is set to "machine system unit" or "combined system unit."
When "motor system unit" is selected, the setting here will be ignored.
BFM No.
High order Low order

#36
Point
When the positioning parameter is used, use the feed rate (BFM#2, #1).
