Manual (Function).)
*2 The open collector transistor is ON (conductive) in LOW state. The transistor is OFF (not conductive) in HIGH state.
*3 To comply with the Low Voltage Directive (conforming standard EN 61800-5-1) and UL or cUL standards (conforming standard UL 61800-
5-1), the operating capacity of the relay outputs (terminal symbols A, B, and C) should be 30 VDC, 0.3 A. (Relay output has basic isolation
from the inverter internal circuit.)

The output is in LOW state when the inverter
output frequency is equal to or higher than the
starting frequency (initial value: 0.5 Hz). The
Inverter running
output is in HIGH state during stop or DC
injection brake operation.
The output is in LOW state when the inverter
output frequency is equal to or higher than the
preset detection frequency, and is in HIGH state
