LSIS G100, Operation Manual

Page: 90 / 343

Take caution on any safety accidents when operating the inverter with Automatic
Restart After Reset enabled as the motor will begin rotating as soon as the inverter is
reset from the terminal block or keypad after a trip occurs.
4.8 Setting Acceleration and Deceleration Times
4.8.1 Acc/Dec Time Based on Maximum Frequency
Acc/Dec time values can be set based on maximum frequency, not on inverter
operation frequency. To set Acc/Dec time values based on maximum frequency, set
bA. 08 (Acc/Dec reference) in the Basic group to 0 (Max Freq).
Acceleration time set at the ACC (acceleration time) code in the Operation group
(dr.03) refers to the time required for the inverter to reach the maximum frequency
from a stopped (0 Hz) state. Likewise, the value set at the DEC (deceleration time)
code in the Operation group (dr.04) refers to the time required to return to a stopped
state (0 Hz) from the maximum frequency.

Description
bA.08
Ramp T Mode
Set the parameter value to 0 (Max Freq) to setup Acc/Dec time based
on maximum frequency.
Configuration Function
0 Max Freq
Set the Acc/Dec time based on maximum
frequency.
1 Delta Freq
Set the Acc/Dec time based on operating
frequency.
If, for example, maximum frequency is 60.00 Hz, the Acc/Dec times
are set to 5 seconds, and the frequency reference for operation is set
