Using Intelligent Input Terminals Terminals [1], [2], [3], [4], [5], [6] and [7] are identical, programmable inputs for general use. The input circuits can use the inverter’s internal (isolated) +24V field supply or an external power supply. This section describes input circuits operation and how to connect them properly to switches or transistor outputs on field devices.
Page 33
The two diagrams below input wiring circuits using the inverter’s internal +24V supply. Each diagram shows the connection for simple switches, or for a field device with transistor outputs. Note that in the lower diagram, it is necessary to connect terminal [L] only when using the field device with transistors.
Page 34
The two diagrams below show input wiring circuits using an external supply. If using the “Sinking Inputs, External Supply” in below wiring diagram, be sure to remove the jumper wire, and use a diode (*) with the external supply. This will prevent a power supply contention in case the jumper wire is accidentally placed in the incorrect position.
Page 35
CAUTION: Be sure to diode in between "P24" and "PLC" when connecting plural inverters with digital input wiring in common. By having ability inverter doesn’t block the current flowing into itself when it is not powered. This may cause the closed circuit when two or more inverters are connected to common I/O wiring as shown below to result in unexpected turning the on the input.
Page 36
Forward Run/Stop and Reverse Run/Stop Commands: When you input the Run command via the terminal [FW], the inverter executes the Forward Run command (high) or Stop command (low). When you input the Run command via the terminal [RV], the inverter executes the Reverse Run command (high) or Stop command (low).

Two Stage Acceleration and Deceleration When terminal [2CH] is turned ON, the inverter Target changes rate acceleration frequency deceleration from the initial settings ( ) to use the second set of acceleration/ second Output deceleration values. When the terminal is initial frequency turned OFF, the inverter is returned to the...
Unattended Start Protection If the Run command is already set when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protection (USP) function prevents that automatic startup, so that the inverter will not run without outside intervention. When USP is active and you need to reset an alarm and resume running, either turn the Run command OFF, or perform a reset operation by the terminal [RS] input or the keypad Stop/reset key.
Reset Inverter The [RS] terminal causes the inverter to execute 12 ms the reset operation. If the inverter is in Trip Mode, minimum [RS] the reset cancels the Trip state. When the signal [RS] is turned ON and OFF, the inverter executes Approx.
Using Intelligent Output Terminals Run Signal When the [RUN] signal is selected as an [FW,RV] intelligent output terminal, the inverter outputs a signal on that terminal when it is in Run Mode. The output logic is active low, and is ...
Page 42
Frequency Arrival Signals The Frequency Arrival group of outputs helps coordinate external systems with the current velocity profile of the inverter. As the name implies, output [FA1] turns ON when the output frequency arrives at the standard set frequency (parameter F001). Output [FA2] relies on programmable accel/ decel thresholds for increased flexibility.
Page 43
Frequency arrival output [FA1] uses the standard output frequency (parameter F001) as the threshold for switching. In the figure to the right, Frequency Arrival [FA1] turns when output Foff Output frequency gets within Fon Hz below or freq. Fon Hz above the target constant frequency, where Fon is 1% of the set Foff...
Alarm Signal The inverter alarm signal is active when a fault has STOP RESET occurred and it is in the Trip Mode (refer to the Stop diagram at right). When the fault is cleared the alarm signal becomes inactive. STOP RESET We must make a distinction between the alarm signal AL and the alarm relay contacts [AL0], [AL1] and [AL2].
Page 45
The alarm relay output can be configured in two main ways: Trip/Power Loss Alarm – The alarm relay is configured as normally closed (=) by default, shown below (left). An external alarm circuit that detects broken wiring also as an alarm connects to [AL0] and [AL1]. After powerup and short delay (< 2 seconds), the relay energizes and the alarm circuit is OFF.
Analog Input Operation AM H O OI L The WJ200 inverters provide for analog input to +V Ref. command the inverter frequency output value. The analog input terminal group includes the [L], Voltage input [OI], [O], and [H] terminals on the control Current input connector, which provide for Voltage [O] or Current [OI] input.
Page 47
The following table shows the available analog input settings. Parameter and the input terminal [AT] determine the External Frequency Command input terminals that are available, and how they function. The analog inputs [O] and [OI] use terminal [L] as the reference (signal return).
Pulse Train Input Operation The WJ200 inverter is capable of accepting pulse train input signals, which are used for frequency command, process variable (feedback) for PID control, and simple positioning. The dedicated terminal is called “EA” and “EB”. Terminal “EA” is a dedicated terminal, and the terminal “EB”...
Analog Output Operation AM H O OI L In inverter applications it is useful to monitor the inverter operation from a remote location or from the Analog front panel of an inverter enclosure.
