15 Multi-speed terminal K4
16
Terminal 1 for
acceleration/
deceleration time
selection
Totally four groups of acceleration/deceleration time can
be selected through combinations states of these two
terminals.
17
Terminal 2 for
acceleration/
deceleration time
selection
18
Frequency source
switchover This terminal is used to perform switchover between two
frequency sources according to the setting in P0.07.
19
UP/DOWN setting
clearance (terminal,
keyboard)
If the frequency source is digital setting, the terminal is
used to clear the modifications by using the UP/
DOWN function or the UP/DOWN key on keyboard,
returning the set frequency to the value of P0.08.
20
Command source
switchover terminal
If the command source is set to terminal control (P0.02
= 1), this terminal is used to perform switchover
between terminal control and keyboard control.
If the command source is set to communication control
(P0.02 = 2), this terminal is used to perform switchover
between communication control and keyboard control.
21
Acceleration/Decelerati
on prohibited
It enables the inverter to maintain the current frequency
output without being affected by external signals (except
the STOP command).
22 PID pause
PID is invalid temporarily. The inverter maintains the
current frequency output without PID adjustment of
frequency source.
23 PLC status reset
The terminal is used to restore the original status of PLC
control for the Inverter when PLC control is started
again after a pause.
24 Swing pause
The inverter outputs the central frequency, and the
swing frequency function pauses.
25 Counter input This terminal is used to count pulses.
26 Counter reset This terminal is used to clear the counter status.
27 Length count input This terminal is used to count the length.
28 Length reset This terminal is used to clear the length.
29
Torque control
prohibited The inverter is prohibited from torque control and enters
the speed control mode.
30
Pulse input enabled
(only for DI5)
DI5 is used for pulse input.
31 Reserved Reserved.
32 Immediate DC braking
The inverter directly switches over to the DC braking
state.
33
External fault normally
closed (NC) input
If this signal is sent to the inverter, the inverter will
output 15=E.EIOF and performs the fault protection
action. For details please check P9.47.
34
Frequency modification
prohibited The inverter does not respond to any frequency
modification.
