Description
14
Terminal 2 for acceleration/
deceleration time selection
15
Frequency source switchover
The terminal is used to perform switchover between two frequency
sources according to the setting in b0-07.
16
Switchover between main
frequency source X and digital
setting frequency
After this terminal becomes ON, the frequency source X is replaced
by the digital setting frequency (b0-12).
17
Switchover between auxiliary
frequency source Y and digital
setting frequency
After this terminal is enabled, the frequency source Y is replaced by
the digital setting frequency (b0-12).
18
Terminal 1 for Command source
switchover
If the command source is set to terminal control (b0-02
= 1), this terminal is used to perform switchover between terminal
control and operation panel control.
If the command source is set to communication control (b0-02 = 2),
this terminal is used to perform switchover between communication
control and operation panel control.
19
Terminal 2 for Command source
switchover
It is used to perform switchover between terminal control and
communication control. If the command source is terminal control, the
system will switch over to communication control after this terminal
becomes ON.
20
Speed control/Torque control
switchover
This terminal enables the frequency inverter to switch over between
speed control and torque control. When this terminal becomes OFF,
the frequency inverter runs in the mode set in d1-00. When this
terminal becomes ON, the frequency inverter switches over to the
other control mode.
21
Torque control prohibited
The Frequency inverter is prohibited from torque control and enters
the speed control mode.
22
PID pause
PID is invalid temporarily. The frequency inverter maintains the
present frequency output without supporting PID adjustment of
frequency source.
23
PID integral pause
After this terminal becomes ON, the integral adjustment function
pauses. However, the proportional and differentiation adjustment
functions are still valid.
24
Reverse PID action direction
After this terminal becomes ON, the PID action direction is reversed
to the direction set in C0-04.
25
PID parameter switchover
If the PID parameters switchover performed by means of DI terminal
(C0-12 = 1). When the terminal becomes OFF; the PID parameters are
C0-06~C0-08; when this terminal becomes ON, the PID parameters
switch to C0-09 ~ C0-11.
26
PLC status reset
The terminal is used to restore the original status of PLC control for
the frequency inverter when PLC control is started again after a pause.
32
Pulse input (enabled only for
HDI/HDI)
HDI is used for pulse input.
33
Frequency modification
forbidden
After this terminal becomes ON, the frequency inverter does not
respond to any frequency modification.
34
Acceleration/Deceleration
prohibited
It enables the frequency inverter to maintain the present frequency
output without being affected by external signals (except the STOP
command).
36
(Reserved)
Reserved.
37
Fault reset (RESET)
The terminal is used for fault reset function, the same as the function
of RESET key on the operation panel. Remote fault reset is
implemented by this function.
38
Normally open (NO) input of
external fault
If this terminal becomes ON, the frequency inverter reports Err15 and
performs the fault protection action. For more details, see the
description of bb-32.
