5-6 Parameters and Programming
Program Group Parameters
This group contains parameters whose values can be programmed. Refer to
Programming Example earlier in this chapter. Unless otherwise stated, parameters
that are programmed while the drive is running take immediate effect.

Default
30 [Accel Time 1]
Time for the drive to ramp from 0.0 Hz. to P33 - [Maximum Frequency]. The rate
is linear for any increase in command frequency unless P53 - [S-Curve] is set to
a value other than “0”. Setting this to 0.0 sec. gives 0.1 sec acceleration with the
initial current limit turned off. This allows quicker acceleration times for low inertia
systems. For medium to high inertia systems, the minimum value should be 0.1
sec.

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”. See P30 - [Accel Time 1] figure above.

➊
[Minimum Frequency]
Lowest frequency that drive will output continuously.
0/240 1 Hz 0 Hz
33
➊
[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].
0/240 1 Hz 60 Hz
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.
0/3 Numeric
Value
0
35 [Base Frequency]
Set value to rated nameplate frequency of motor. A Program Keypad Module is
required if P35 must be changed to 50 Hz.
10/240 1 Hz 60 Hz
➊
The 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].
