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.

speed command
You can set up the relation between the voltage applied to the speed
command input (SPR : CN X5, Pin-14) and the motor speed.
• You can set up a "slope" of the relation
between the command input voltage
and the motor speed, with Pr50. 
• Default is set to Pr50=500 [r/min],
hence input of 6V becomes 3000r/min.
<Cautions>
1. Do not apply more than ±10V to the
speed command input (SPR). 
2. When you compose a position loop
outside of the driver while you use the
driver in velocity control mode, the
setup of Pr50 gives larger variance to
the overall servo system.
Pay an extra attention to oscillation caused by larger setup of Pr50.
