Inverter running [RUN]
"Inverter running" means that the inverter
outputs a frequency as a speed signal. At this
time, an ON signal is output. However, if the DC
braking function is active, the signal is turned
off.
Frequency equivalence [FAR]
Refer to the description for function code E30
Frequency equivalence (detection width).
Frequency level detection [FDT]
Refer to the description for function codes E31
and E32 Frequency level detection.
Undervoltage detection signal [LV]
When the undervoltage protection function is
active, that is, when the main circuit DC voltage
is below the undervoltage detection level, an
ON signal is output. After the voltage is restored
to become higher than the undervoltage
detection level, the signal is turned off. The ON
signal is output also during activation of the
undervoltage protection function.
Undervoltage detection level:
Approx 200 Vdc (200V class)
Approx 400Vdc (400V class)
PID control cancel [Hz/PID]
An external digital input signal can disable PID
control.
Inverse mode changeover (Terminal 12 and
C1) [IVS]
An external digital input signal switches
between the forward and reverse operations of
analog inputs (terminals 12 and C1).
Link enable (RS485) [LE]
An external digital input signal is switched to
validate or invalidate the frequency command
and operation command from the link. The
source of the command can be set at H30 Link
function.
Acceleration time 2
Deceleration time 2
•
Additional acceleration and deceleration time
can be selected besides F07 "Acceleration
time 1" and F08 "Deceleration time 1".
•
The operation and setting range are the same
as those for F07 "Acceleration time 1" and
F08 "Deceleration time 1". Refer to these
functions.
•
To switch between the acceleration and
deceleration time, select any terminal from
among E01 "X1 terminal (Function selection)"
through E05 "X5 terminal (Function selection)"
as a switching signal input terminal. Set the
selected terminal to "4"
(acceleration/deceleration time selection) and
supply a signal to the terminal to switch.
Switching is effective during acceleration,
during deceleration or during constant speed
operation.
E11
E10
Torque limiter 2 (Driving)
Torque limiter 2 (Braking)
•
Use these functions to switch the torque
limiter levels set at F40 and F41 using an
external control signal. The external signal is
supplied to an arbitrary control terminal
among X1 through X5, the function of which
is set to torque control 2 / torque control 1
(data 12) at E01 to E05.
Y1 terminal function
Y2 terminal function
•
A part of control and monitor signals can be
output at the Y1 and Y2 terminals.
