Parameters and Programming
31
[Decel Time 1]
Time for the drive to ramp from P33 - [Maximum Frequency] to 0.0 Hz. The rate
is linear for any decrease in command frequency unless P53 - [S-Curve] is set
to a value other than 0.
➊
Minimum deceleration time must be set based on the applied motor size.
To guard against premature drive failure, do not set P31 - [Decel Time 1] or
P70 - [Decel Time 2] below the minimum value listed in the table below.

[Minimum Frequency]
Lowest frequency that drive will output continuously.

[Maximum Frequency]
Highest frequency the drive will output.
This parameter cannot be changed while running. The value of this parameter
setting must be greater than the value set in P32 - [Minimum Frequency].

34
[Stop Mode Select]
Determines stopping mode used by the drive when a stop is initiated. Refer to
the P44 - [DC Hold Time] and P45 - [DC Hold Voltage] diagrams.
Settings:
0 Ramp to Stop
1 Coast to Stop
2 DC Injection Braking
3 DC Injection Braking (w/Auto Shutoff) – works the same as standard DC injection
braking except that it may shut off before the P44 - [DC Hold Time]. This occurs
if the drive is out of current limit before the P44 - [DC Hold Time] expires.

35
[Base Frequency]
Set value to rated nameplate frequency of motor. A Program Keypad Module,
Remote Keypad Module or CopyCat Keypad Module is required if P35 must be
changed to 50 Hz.

Sets the highest voltage that the drive will output. P37 - [Maximum Voltage] must
be greater than or equal to P36 - [Base Voltage].

➋The analog inputs to the drive (i.e. 4-20mA, 0 to +10 V, or remote potentiometer) can be scaled to P32 - [Minimum Frequency] and
P33 - [Maximum Frequency] by programming P75 - [Analog Input Minimum] and P76 - [Analog Input Maximum].
