: Relays
■ Terminal’s default function
[RUN:001]Running
• Turns ON during operation (PWM output).
[FA1:002]Constant-frequency reached
• Turns ON when the output frequency reaches the control
frequency.
[FA1:003]Set frequency overreached
• Turns ON when the output frequency reaches the control
frequency [CE-10]/ [CE-11].
[IRDY:007]inverter ready
• Turns ON when is ready for operation.
[OL:035]Overload notice advance signal
• Turns ON when the current exceeds the overload warning
level.
[ZS:040]Zero speed detection
• Turns ON when the output frequency goes below the Zero
speed detection level [CE-33].
[***] it means factory default settings.

Output terminal
Terminal functions are selectable
according to the parameter settings
for each terminal.
This is available for both SINK and
Source logics.
Open collector output
Between each terminal and CM2
• Voltage drop when turned on: 4 VDC or less
• Max. allowable voltage 27VDC
• Max. allowable current 50mA
CM2
Output
(common)
This is a common terminal for output
terminals 11 to 15.
