]
Parameter # 19 Factory Default 60 Hz
[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.
[Sto

Parameter # 10 Factory Default ‘‘Ramp”
[Stop
Select]
Parameter Type Read & Write
This parameter selects the stopping mode when the drive
receives a valid sto
p
command.
Units Text Settings ‘‘Coast”

a
valid
stop
command
.
‘‘Ramp” Drive Decelerates to 0 Hz, Then Turns
Off – Requires a Value In
[Decel Time 1] or [Decel Time 2]
‘‘DC Brake”
Injects DC Braking Voltage Into the
Motor – Requires a Value in Both
[Decel Hold Time] & [Decel Hold
Level].
‘‘S-Curve”
Drive ramps to stop using ‘fixed S-Curve’
profile. Stop time is twice the selected
decel time.

Current Limit
]
Parameter # 36 Factory Default 150 % of Drive Rated Current ➀
[Current
Limit]
Parameter Type Read & Write Minimum 20 % of Drive Rated Current ➀
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.
➀ The Drive Rated Ouput Current is based on three phase input ratings. See page 5-13 for instructions for Single Phase Input Ratings.
