Common Terminals (Sd, 5, Se); Signal Inputs By Contact-Less Switches - Mitsubishi Electric FR-V560 Instruction Manual

Input terminals

1.10.6 Common terminals (SD, 5, SE)

Terminals SD, 5 and SE are all common terminals (0V) for I/O terminals and the other common terminals are
isolated from each other.
Terminal SD is a common terminal for the contact input terminals (STF, STR, OH, RES, DI1, DI2, DI3 and DI4) and
the encoder output signals. When using the terminal SD as a common terminal for the encoder output signals, use
a shielded or twisted cable to protect it from external noise.
Terminal 5 is a common terminal for the speed setting analog input signals and analog output signals. Use a
shielded or twisted cable to protect it from external noise.
Terminal SE is a common terminal for the open collector output terminals (DO1, DO2, DO3).

1.10.7 Signal inputs by contact-less switches

If a transistor is used instead of a contacted
switch as shown on the right, the input signals of
the inverter can control the STF, STR, OH, RES,
DI1, DI2, DI3 and DI4 terminals.
Input resistance : 4.7kΩ
Voltage when contacts are open : 21 to 27VDC
When contacts are short-circuited : 4 to 6mADC
REMARKS
• When using an external transistor connected to the external power supply, use terminal PC to prevent a
malfunction due to a sneak current.
(Refer to page 17 for details.)
• Note that when off, an SSR (solid-state relay) has a relatively large leakage current and it may be accidentally
input to the inverter.
