Analog Output Signal For Dancer Tension Setting (Pr. 718, Pr. 719, Pr. 733, Pr. 734, Pr. 785, Pr. 787 To Pr. 789) - Mitsubishi Electric FR-A700-A1 Instruction Manual

3.10.6 Analog output signal for dancer tension setting (Pr. 718, Pr. 719, Pr. 733, Pr. 734,
Pr. 785, Pr. 787 to Pr. 789)
Dancer is controlled with an air cylinder. Set an analog signal, which is output for tension setting to control the air cylinder,
with terminal FM/AM.
