PARAMETER
(3) Reference of torque monitor [Pr. 866]
For the calibration of terminal FM, set the full-scale
value of the connected torque meter when the pulse
speed of terminal FM is 1440 pulse/s (50k pulse/s
when high speed pulse train output is selected in
). Set the torque to be indicated as the full
scale value on the torque meter (1mA analog meter)
connected between terminal FM and SD. Pulse
speed is proportional to the monitored value of
torque. (Maximum pulse train output is 2400 pulse/s
(55k pulse/s when high speed pulse train output is
selected on
)).
For the calibration of terminal AM, AM0 and DA1, set
the full-scale value of the connected torque meter
when the output voltage of the terminal AM, AM0 and
DA1 are 10VDC. Set the torque to be indicated as
the full scale value on the meter (10V analog meter)
connected between terminal AM and 5 (AM0 and
AMC, DA1 and 5). Output voltage is proportional to
the monitored value of torque.(Maximum output
voltage is 10VDC.)
For the calibration of terminal AM1, set the full-scale
value of the connected torque meter when the output
current of the terminal AM1 is 20mADC. Set the
torque to be indicated as the full scale value on the
meter (20mA analog meter) connected between
terminal AM1 and AMC. Output current is
proportional to the monitored value of torque.
(Maximum output current is 20mADC.))
(4) Terminal AM response adjustment [Pr.
867]
Using [ Pr. 867 ], the output voltage response of
terminal AM can be adjusted within the range 0 to 5s.
Increasing the setting stabilizes the terminal AM
output more but reduces the response level. (Setting
0 sets the response level to 4ms)
(5) Terminal DA1 (FR-A7AZ) response
adjustment [Pr. 839]
Using [ Pr. 839 ], the output voltage response of
terminal DA1 can be adjusted within the range 0 to
5s.
Increasing the setting stabilizes the terminal DA1
output but reduces the response level.
[
Pr. 839 DA1 output filter ] setting plus 5ms at
maximum equals to the response time of terminal
DA1.
