*The function of this terminal will change when the commercial power supply operation-inverter
operation switch-over function is selected. (Refer to page 83.)
**Low indicates that the open collector outputting transistor is on (conducts). High indicates that the
transistor is off (does not conduct).
***The output of these terminals can be reassigned by the output terminal assignment function (see
By entering 0 to 5VDC (0 to IOVDC), the maximum output frequency is
reached at 5V (or 10V) and I10 are proportional. Switch between input 0 to
5VDC (factory setting) and 0 to lOVDC from the parameter unit. lnput resis-
tance 10kQ. Max. permissible voltage 20VDC.
By entering 4 to 20mADC, the maximum output frequency is reached at
20mA and I10 are proportional. This input signal is valid only when the sig-
nal across terminals AU and SD is on. lnput resistance 250Q. Max. permissi-
ble current 30mA.
By entering 0 to +5VDC 0 to klOVDC, this signal is added to the frequency
setting signal of terminal 2 or 4. Switch between input 0 to k5VDC (factory
setting) and 0 to +10VDC (factory setting) from the parameter unit. lnput re-
sistance 10kQ. Max. permissible voltage 20VDC.
Common to the frequency setting signals (terminals 2, 1 or 4) and analog
output terminal AM. O V line of the common circuit of the control circuit. Do
not ground.
Change-over contact output indicating that the output has been stopped by
the inverter protective function activated.
200VAC 0.3A, 3OVDC 0.3A. Alarm: discontinuity across B-C (continuity
across A-C), normal: continuity across B-C (discontinuity across A-C).
Switched low when the inverter output frequency is equal to or higher than
the starting frequency (factory set to 0.5Hz, variable). Switched high during
stop or DC injection brake operation (**). Permissible load 24VDC 0.1A.
Switched low when the output frequency has reached within + l o % of the
set frequency (factory setting, variable). Switched high during acceleration,
deceleration or stop ("). Permissible load 24VDC 0.1A.
Switched low when the current limit function has caused stall prevention to
be activated. Switched high when stall prevention is reset (").
Permissible
load 24VDC 0.1A.
Switched low when instantaneous power failure or undervoltage protection
is activated (**). Permissible load 24VDC 0.1A.
Switched low when the output frequency has reached or exceeded the de-
tection frequency set optionally. Switched high when below the detection fre.
quency ("). Permissible load 24VDC 0.1A
Common to the RUN, SU, OL, IPF and FU terminals. Isolated from the com-
mon circuit of the control circuit.

same time.
