*1: The maximum (minimum) value of the armature current limit varies with the model of VF66B (DC motor drive)
・
For models less than 7522, 7544
The value is calculated by 200 x (
rated current of VF66B (DC motor drive)
/rated motor armature current (A-04).
If the calculated value exceeds 200%, the maximum (minimum) value is 200%.
・
For models greater than or equal to 7522, 7544
The value is calculated by 150 x (
rated current of VF66B (DC motor drive)
/rated motor armature current (A-04).
If the calculated value exceeds 200%, the maximum (minimum) value is 200%.
Forward powering armature current limit (b-13) to reverse regenerative armature current limit (b-16):
In these parameters, set armature current limits of power running and regeneration for each of forward
rotation and reverse rotation. When an armature current command exceeds any of these values, it is limited to
these setting values. Incidentally, the rated current of VF66B (DC motor drive) is 100%.

Analog input (1) characteristics selection (b-17):
In this parameter, select the type of input characteristics of analog input (1) of [VFC66-Z TB1] (AIN1).
Analog input (1) speed/voltage upper limit (b-18), analog input (1) speed/voltage lower limit (b-19):
Settings for the analog input (1) speed/voltage upper limit (b-18) and analog input (1) speed/voltage lower
limit (b-19) vary depending on the operation mode selection (i-07).
・
When the operation mode selection is speed control mode (i-07 = 0)
Set the ratio to the maximum speed (A-00).
・
When the operation mode selection is armature voltage control mode (i-07 = 5)
Set the ratio to the forward direction output maximum voltage (E-11) or reverse direction output maximum
voltage (E-12) whichever its absolute value is larger.
