(M) Monitor display and monitor output signal
When outputting such an item as the output current, which cannot reach a 100% value easily by
operation, set Pr. 54 to "21" (reference voltage output) and calibrate. 1440 pulses/s are output
from the terminal FM.
When Pr. 310 "Analog meter voltage output selection" = "21", the terminal FM calibration cannot
be performed. For the details of Pr. 310, refer to the Instruction Manual of FR-A8AY.
The wiring length of the terminal FM should be 200 m at maximum.
The initial value of the calibration parameter C0 (Pr. 900) is set to 1 mA full-scale and 1440 pulses/s
terminal FM pulse train output at 60 Hz. The maximum pulse train output of terminal FM is 2400
When connecting a frequency meter between terminals FM-SD and monitoring the running fre-
quency, it is necessary to change Pr. 55 to the maximum frequency, since the FM terminal output
will be saturated at the initial value when the maximum frequency reaches 100 Hz or greater.
Calibration with the calibration parameter C0 (Pr. 900) cannot be done when Pr. 291 "Pulse train I/O
selection" = "10, 11, 20, 21, 100" (high-speed pulse train output).
