FM Analog monitor The monitor signal for analog DC voltage (0 to +10
Vdc) is output. The signal description can be
selected from the following.
• Output frequency1 (before slip compensation)
• Output frequency2 (after slip compensation)
• Output current • Output voltage
• Output torque • Load factor
Analog • Input power • PID feedback value
output/ • DC link circuit voltage
pulse * Allowable connection impedance: min. 5 k ohm
output
Pulse rate monitor The monitor signal is output according to the pulse
voltage. The signal description is the same as the
FMA signal.
* Allowable connection impedance: min. 5 k ohm
Use SW1 on the control board and function code
F29 to change between the analog monitor and
Pulse rate monitor.
(FMA: analog monitor, FMP: Pulse rate monitor)
Y1E Transistor output 1 The RUN signal, frequency equivalence signal,
Y2E Transistor output 2
overload early warning signal and other signals are
output to arbitrary ports at a transistor output.
Refer to terminal function E20 to 21 setting
methods in section 5-2 Detail Description of Each
Function.
<Transistor output circuit specification>
Transistor
output
CMC Common Common for transistor output signal. Isolated from
(Transistor output) terminals CM and 11.
P24 DC voltage supply Power supply for transistor output load. (24 Vdc 50
mAdc Max.) (When using P24, short the CMC and
P24 terminals) (If the P24 terminal is overloaded or
connected with the CM terminal, the inverter trips
with Er3 indication. To reset, remove external
causes and, after several minutes, turn the inverter
on again.)
30A,30B, Alarm relay output When the inverter is stopped with an alarm, a relay
30C contact output (1C) is issued.
Relay Contact capacity: 48 Vdc 0.5 A
output (When complying with UL/cUL:42Vdc 0.5A)
Selection between excitation upon an alarm or
excitation during normal operation is possible.
