Block diagram
The frequency command/torque command responsiveness and stability are adjustable by using the analog input
(terminals 1, 2, and 4) signal.
Pr. Name Initial value Setting range Description
74
T002
Input filter time constant
1 0 to 8
The primary delay filter time constant to
the analog input is selectable. The higher
the value, the lower the responsiveness.
822
T003
Speed setting filter 1
9999
0 to 5 s
Set the primary delay filter time constant
to the external speed command (analog
input command).
9999 Use the Pr.74 setting.
826
T004
Torque setting filter 1
9999
0 to 5 s
Set the primary delay filter time constant
to the external torque command (analog
input command).
9999 Use the Pr.74 setting.
832
T005
Speed setting filter 2
9999 0 to 5 s, 9999
Second function of Pr.822 (enabled when
the RT signal is ON)
836
T006
Torque setting filter 2
9999 0 to 5 s, 9999
Second function of Pr.826 (enabled when
the RT signal is ON)
849
T007
Analog input offset
adjustment
100% 0 to 200%
Make the analog speed input (terminal 2)
have an offset. This prevents the motor
from rotating by noise to the analog input
or another cause on the speed 0
command.
