• Pulse generator magnification response (Ver.1.10 or later)
For the relationship between the response and input pulses/output pulses, refer to the figure below.
The response setting does not affect the output pulse frequency and pulse quantity.

Input pulses
(frequency, pulse quantity)
A-phase

Caution
An error may occur when the response is drastically changed from low to high or from high to low while the
manual pulse generator is operating.

BFM Number
X-axis Y-axis
Sets the MPG response (Ver.1.10 or later)
The set value can be changed even during operation.
• If the set value is smaller, the follow-up capability of output pulses to manual
pulse generator inputs is higher.
BFM #528 BFM #628 However, note that the machine may be overloaded if the speed is changed
drastically.
• If the set value is larger, the follow-up capability of output pulses to manual
pulse generator inputs is lower, but the machine gives smoother motions
(outputs).
