[Maximum Freq]

Parameter Type Read & Write

Minimum 40 Hz

This parameter sets the highest frequency the drive will
output. IMPORTANT: All analog inputs to the drive
(4-20mA, 0-10V, Remote Pot) are scaled for the range
[Minimum Freq] to [Maximum Freq]. Max hertz may be
set to less than base hertz.

Units 1 Hz

Maximum 400 Hz

IMPORTANT: This parameter can
not be programmed while the
drive is running.

[Stop Select]

Parameter # 10

This parameter sets the maximum drive output current that
is allowed before current limiting occurs. IMPORTANT: If a
value is programmed into the [Sec Curr Limit] parameter
then that value will be the active current limit value at
speeds above 1.5 times [Base Frequency]. See Fig. 5.5.
[Output 1 Config] and [Output 2 Config] can be set to
‘‘alarm” to indicate an overload condition exists.

Units 1 %

Maximum 150% of Drive Rated Current ➀

IMPORTANT: See [Cur Lim Trip En] on page 5-40.
