Parameters and Programming
5-13
[Preset Frequency 0-7]
The programmed value sets the frequency that the drive outputs when selected.
Refer to Chapter 2, Figure 2.21 for the Preset Speed model control wiring diagram.

69
[Accel Time 2]
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 gives 0.1 seconds 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.

[Decel Time 2]
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.
➋
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.
