Time scale
Use the time scale for all time-related values. It is particularly useful when a
more accurate Acc/Dec times are required because of load characteristics,
or when the maximum time range needs to be extended.
Configuration
Description
0
0.01 sec
Sets 0.01 second as the minimum unit.
1
0.1 sec
Sets 0.1 second as the minimum unit.
2
1 sec
Sets 1 second as the minimum unit.
5.1.2.2 Acc/Dec Time based on Operating Frequency
Acc/Dec times can be set based on the time required to reach the next step frequency from the
existing operation frequency. Set BAS-08 (acc/dec reference) to ‘1 (Delta Freq)’.

Acc/Dec Time Based on Operation Frequency – Setting Details
Code
Description
Set the parameter value to 1 (Delta Freq) to set Acc/Dec times based on
Maximum frequency.
Configuration
Description
0
Max Freq
Set the Acc/Dec time based on Maximum frequency.
1
Delta Freq
Set the Acc/Dec time based on Operation frequency.
Note that the range of maximum time values may change automatically when the units are
changed. If for example, the acceleration time is set at 6000 seconds, a time scale change from 1
second to 0.01 second will result in a modified acceleration time of 60.00 seconds.
