Reversal of pulse
output logic
You can set up the B-phase logic and the output source of the pulse output (X5 OB+
: Pin-48, OB– : Pin-49). With this parameter, you can reverse the phase relation
between the A-phase pulse and the B-phase pulse by reversing the B-phase logic.
*1 The output source of Pr46=2, 3 is valid only at full-closed control.

Electronic gear (Command pulse division/multiplication) function
• Purpose of this function
(1) You can set up any motor revolution and travel per input command unit.
(2) You can increase the nominal command pulse frequency when you cannot
obtain the required speed due to the limit of pulse generator of the host controller.
• Block diagram of electronic gear
• "Numerator" selection of electronic gear

) is automat-
ically set equal to encoder resolution,
and you can set command pulse per
revolution with Pr4B.
The electronic gear ratio is set with the formula below.
