Setting using Pr. 55, Pr. 56
Set to make the PU
level meter indication
to be in full-scale.
Set to make the
terminal FM pulse train
output to be 1440
pulses/s.
Set to make the
terminal AM output
voltage to be 10V.
Note: 1. The maximum pulse train output of terminal FM is 2400 pulses/s. If Pr. 55 is not adjusted, the
output of terminal FM will be filled to capacity. Therefore, adjust Pr. 55.
2. The maximum output voltage of terminal AM is 10VDC.
