Analog
monitor
The monitor signal for analog DC voltage (0 to +10 VDC) is output. The
signal functions can be selected from the following with function code F31.
- Output frequency (before slip compensation)
- Output frequency (after slip compensation)
- Output current - Output voltage
- Input power - PID feedback amount
- DC link bus voltage - Calibration
- PID command (SV) - PID output (MV)

Common terminal for analog input and output signals
This terminal is electrically isolated from terminals [Y1E].

(1) Various signals such as "Inverter running," "Frequency arrival signal" and
"Motor overload early warning" can be assigned to terminal [Y1] by setting
function code E20. Refer to Chapter 5, Section 5.2 "Details of Function
Codes."
(2) Switches the logic value (1/0) for ON/OFF of the terminals between [Y1]
and [Y1E]. If the logic value for ON between [Y1] and [Y1E] is 1 in the
normal logic system, for example, OFF is 1 in the negative logic system
and vice versa.
Digital input circuit specification
Figure 2.9 shows examples of connection between the control circuit and a
PLC.
- Check the polarity of the external power inputs.
- When connecting a control relay, first connect a
surge-absorbing diode across the coil of the
relay.
[PLC]
Transistor
output
power
Power source of +24 VDC to be fed to the transistor output circuit load (50 mA
at maximum).
To enable the source, it is necessary to short-circuit between terminals [Y1E]
and [CM].
Can also be used as a 24 VDC power source.
