37 [Maximum Voltage]
Sets the highest voltage that the controller will
output.
P37 – [Maximum Voltage] must be greater than or equal to P36 – [Base Voltage].
20 to 510 for
460V units and
20 to 255 for
230V units
1 Volt 460 Volts for
460V units
and 230 for
230V units
38 [Boost Select]
Sets the boost voltage and redefines the Volts per Hz
curve.

40 [Skip Frequency Band]
Determines the band around the P39 –
[Skip Frequency] parameter. The actual band width will be 2 times [Skip
Frequency Band] – 1/2 the band above and 1/2 the band below. A value of zero
will disable the skip frequency.
