REMARKS
For the input terminal function switchover timing, refer to page 45.
(2) Control circuit terminal layout
Terminal screw size : M3.5
Tightening torque : 1.2N·m
When connecting three or more control cables
to the terminal 5, connect the accessory
terminal 5 dedicated L-shaped jumper to the
terminal 5.
In this case no cable should be connected to
the screw in the part.
(3) Wiring instructions
1) Terminals 5, SD and SE are common to the I/O signals and isolated from each other. Do not earth (ground)
these terminals. Avoid connecting the terminal SD and 5 and the terminal SE and 5.
2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main
and power circuits (including the 200V relay sequence circuit).
3) Since the control circuit input signals are micro currents, use two or more parallel micro signal contacts or a
twin contact to prevent a contact fault.
4) It is recommended to use the cables of 0.75mm
cable gauge used is 1.25mm
cables are run improperly, resulting in an control panel or parameter unit contact fault.
5) The maximum wiring length should be 30m.
1 changeover contact output indicates that the inverter protective function activated
and the output stopped.
230VAC 0.3A, 30VDC 0.3A. Alarm: discontinuity across B-C (continuity across A-C),
Normal: continuity across B-C (discontinuity across A-C).
The function of the terminals changes according to the output terminal function
selection (Pr. 195) setting.
Refer to page 65 for details.
Permissible load 24VDC 0.1A
The terminal functions vary with the output terminal function selection (Pr. 190 to Pr.
192) settings. Refer to page 65 for details.
Common terminal for terminals DO1, DO2 and DO3. Isolated from terminals SD and
5.
One selected from the monitoring items,
such as the speed, is output.
The output signal is proportional to the
magnitude of the corresponding monitoring
item.
Common terminal for DA1 and DA2.
Isolated from terminals SD and SE.
Do not earth (ground).
With the PU connector, communication can be made through RS-485.
