When using current input as the
frequency setting signal, set "4"
in any of Pr. 60 to Pr. 63 (input
terminal function selection) and
assign AU (current input selection)
to any of terminals RH, RM, RL
and STR.

Remarks
*1 Only the type with RS-485 communication function
*2 You can switch between the sink and source logic positions. For details, refer
to the instruction manual (detailed).
*3 When the setting potentiometer is used frequently, use a 2W1kΩ potentiometer.
• The output is three-phase 200V.
CAUTION
• Keep the signal cables more than 10cm (3.94inches) away from the power cables.
• To ensure safety, connect the power input to the inverter via a magnetic
contactor and earth leakage circuit breaker or no-fuse breaker, and use the
magnetic contactor to switch power on-off.
