When set to Edge-r, if drive is powered up with Digital Input 1 closed (enabled), drive will not

Voltage / Frequency (V/f) Characteristic
Adjusted
The V/f characteristic is defined by several parameters as shown.
Reducing the voltage at a particular frequency reduces the current in
the motor and hence the torque and power; for fans and certain types
of pump which require very little torque at low speed use fan/ pump
curve, P-06=1, HVAC.
The V/f curve can be further modified by using P-26 and P-29, where
P-26 determines the percentage increase or decrease of the voltage
P-26 applied to the motor at the frequency specified in P-29. This can be
useful if motor instability is experienced at certain frequencies, if this
is the case increase or decrease the voltage (P-26) at the speed of
P-29 P-09 P-01 instability (P-29).
