Forward direction output maximum voltage (E-11), reverse direction output maximum voltage (E-12):
In these parameters, set the maximum voltages VF66B (DC motor drive) can output. When a voltage
command is larger than these setting values, the voltage command is limited to one of the setting values.
When voltage commands are limited to the setting value for 500 ms continuously, protective detection is
performed by VF66B (DC motor drive) output overvoltage protection (oV_o) operation.
Incidentally, the forward direction output maximum voltage (E-11) and reverse direction output maximum
voltage (E-12) become the rated motor armature voltage (A-03) when they are set to 100%.

Limit width of the voltage corresponding to the speed (E-13):
When the operation mode selection is speed control (ASR) mode, speed control (ASR) and armature current
control (ACR) with priority to reverse direction, or speed control (ASR) and armature current control (ACR)
with priority to forward direction (i-07 = 0 to 2), this function compares the voltage equivalent to the speed
detected by PG mounted on the motor with the armature voltage command, and when the armature voltage
command exceeds the value calculated by adding the voltage equivalent to the speed and the limit width of
the voltage corresponding to the speed (E-13), this function limits the armature voltage command to the value
calculated by adding the voltage equivalent to the speed and the limit width of the voltage corresponding to
the speed (E-13). When armature voltage commands are limited to the value calculated by adding the voltage
equivalent to the speed and the limit width of the voltage corresponding to the speed (E-13) for 100 ms
continuously, protective detection is performed by PG error protection (PEr) operation.
