4.21.4 Response level of analog input and noise elimination
(Pr. 74, Pr. 822, Pr. 826, Pr. 832, Pr. 836, Pr. 849)
Response level and stability of frequency reference command and torque reference command by analog input
(terminal 1, 2, 4) signal can be adjusted.

Initial Setting
Value Range
The primary delay filter time constant for the analog input
1 0 to 8
can be set. A larger setting results in slower response.
Set the time constant of the primary delay filter relative to
0 to 5s
the external speed command (analog input command).
9999
9999 Pr. 74 used
Set the time constant of the primary delay filter relative to
0 to 5s
the external torque command (analog input command).
9999
9999 Pr. 74 used
9999 0 to 5s, 9999 Second function of Pr. 822 (valid when RT terminal is on)
9999 0 to 5s, 9999 Second function of Pr. 826 (valid when RT terminal is on)
This function provides speed command by analog input
100% 0 to 200% (terminal 2) with offset. Motor rotation due to noise, etc.
by analog input can be avoided at zero speed command.
RT-OFF
Pr. 822 = 9999
Pr. 822 9999
Pr. 826 = 9999
Pr. 826 9999
Pr. 832 = 9999
RT-ON
Pr. 832 9999
Pr. 836 = 9999
Pr. 836 9999
