Function
description
You can set-up the relationship between the motor speed and the
voltage applied to the velocity command input (SPR: CN I/F Pin
14).
You can invert the polarity of the velocity command input (SPR).
Use this parameter in such a case as you want to change the
motor rotating direction without changing the polarity of the com-
mand signals from the controller.
<Notes>
The default of this parameter is 1, i.e. CW rotation with (+) com-
mand. Note that the conventional versions of MINAS series driv-
ers have the same default setting.

・
・ Pr50 defines the gradient
"rpm/command voltage".
・The default of Pr50 is 500
[(r/min)/V], e.g. 6V with 3000 r/min.
<Notes>
1.Don't apply more than ?10V to the velocity command input (SPR).
2.If the position loop is composed externally, the set-up value of Pr50 affects the
overall position gain. Higher set-up of Pr50 could cause oscillation.

<Notes>
When the driver is used at velocity control mode, in combination with the external
positioning unit, pay extra attention to the case when the polarity of this parameter
does not match to that of the velocity signal from the positioning unit. This could
cause the motor malfunction.
