Analog Input Signals And Pulse Train Input Signals - Mitsubishi Electric A800 Plus Series Function Manual

3.3.1
Analog input signals and pulse train input
signals
• Refer to the following table and set the parameters to input the signals.
• For analog input terminals, calibration is available with maximum and minimum input values. Either voltage or current
signals are input through terminal 2 and terminal 4. Always calibrate the terminal after changing the input specification. For
details on selecting the input specification and calibrating input values, refer to the FR-A800 Instruction Manual (Detailed).

∗1 The FR-A8AZ plug-in option is required.
∗2 The FR-A8AP/FR-A8AL plug-in option or the FR-A8TP control terminal option is required.
∗3 The setting is valid when Pr.291="1, 11, 21, or 100".
NOTE
• The Pr.361 to Pr.364 (dedicated function selection) and Pr.1285 settings have higher precedence over the other assigned
terminal settings such as Pr.868, Pr.858, and Pr.406. (Example: When Pr.363="5", and Pr.868="0", terminal 1 is set to the
dancer signal input.)
• While tension sensorless torque control is valid, the following parameter settings are invalid: Pr.361 Line speed command
input selection, Pr.363 Dancer / tension sensor feedback input selection, and Pr.364 Dancer tension setting input
selection.
• The dedicated function parameters take the following precedence over each other. When two or more signals are assigned to
a terminal, a signal with lower precedence is ineffective.
Dancer signal input (Pr.363) > Actual line speed input (Pr.362) > Tension command input (Pr.804) > Line speed command
≠
input (Pr.361 0) > Taper setting input (Pr.1285) > Dancer tension setting input (Pr.364) > Line speed command
compensation input > Line speed command input (Pr.361=0) = Speed command during speed control
• When Pr.361 Line speed command input selection="0" while tension sensorless torque control is valid, the line speed
command is input in the same way as the frequency command.
