Analog output
[FMA]
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
- Power consumption
- PID feedback value
- Intermediate dc circuit voltage
- Analog output test (+)
*Input impedance of external device: Max. 5 kΩ

Analog common
Common terminal for analog input and output signals
Transistor Output
[Y1]
Transistor output (1) Various signals such as drive run status, speed/freq. arrival and overload early warning can
be assigned to the terminal [Y1] by setting function code E20. Refer to the Section 5.2 in
Chapter 5 titled “Overview of Function Codes” for details.
(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.

Note: 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.

Common terminal for transistor output signal
(Isolated from terminals [CM] and [11].)
Relay output
[30A], [30B],
[30C]
Alarm relay
output
(for any fault)
(1) Outputs a contact signal [1C) (SPDT) when a protective function has been activated to stop
the motor.
Contact rating: 250 Vac 0.3 A cos (= 0.3), 48 Vdc, 0.5A
(2) A command similar to terminal [Y1] can be selected for the transistor output signal and use
it for signal output.
(3) Switching of the normal/negative logic output is applicable to the following two contact
outputs: “Terminals [30A] and [30C] are short-circuited for ON signal output” or “the
terminals [30B] and [30C] are short-circuited (non-excite) for ON signal output.”

cations I/O
(1) Used to connect the drive with PC or PLC using RS485 port.
(2) Used to connect the drive with the remote keypad. The drive supplies the power to the
remote keypad through the extension cable for remote keypad.
* This terminal can be used with standard drives equipped with an RS485 communications card (option).
NOTE: Route the wiring of the control terminals as far from the wiring of the main circuit as possible in order to
prevent malfunctioning resulting from interference and noise.
Fix or bind the control cables inside the drive so that they are kept away from the live parts of the main circuit (such
as the main circuit terminal block).
