Building Interface Circuits with External Devices
Using Input Signals
The functions of multi-function input terminals S2 to S5 can be changed as necessary by setting constants n36 to n39. The same value cannot be set for more than one of these constants.

WARNING
To select the 3-wire sequence, set terminal S3 (n37) to
0.
Failure to observe this warning may result in injury.
LOCAL/REMOTE Selection (Setting: 17)
Select the operation reference from either the Digital Operator or from the settings of the RUN Command Selection (n02) and Frequency Reference Selection (n03). The LOCAL/REMOTE Selection can be used only when stopped.
Open: Run according to the setting of RUN Command Selection
(n02) or Frequency Reference Selection (n03).
Closed: Run according to the frequency reference and RUN command from the Digital Operator.
Example: Set n02=1, n03=2, n07=0.
Open: Run according to the frequency reference from multi-function input terminal FR and RUN command from multi-function input terminals S1 to S5.
Closed: Run according to the potentiometer frequency reference and
RUN command from the Digital Operator.
UP/DOWN Commands (Setting: n39 = 034)
When the FWD (REV) RUN command is ON, acceleration/deceleration is enabled by inputting the UP or DOWN signal from multi-function input terminals S4 and S5 without changing the frequency reference.
Operation can thus be performed at the desired speed. When UP/
DOWN commands are specified in n39, any function set in n38 is disabled, terminal S4 is the input terminal for the UP command, and terminal S5 is the input terminal for the DOWN command.

Time Chart for UP/DOWN Command Input

U = UP (accelerating) status
D = DOWN (decelerating) status
H = HOLD (constant speed) status
U1 = UP status, clamping at upper limit speed
D1 = DOWN status, clamping at lower limit speed
Note: 1. When UP/DOWN commands are selected, the upper limit speed is set regardless of frequency reference.
Upper limit speed =Maximum Output Frequency (n09)
× Frequency Reference Upper Limit (n30)/100%
2. Lower limit value is either the Minimum Output Frequency (n14) or
Maximum Output Frequency (n09) × Frequency Reference Lower
Limit (n31)/100% (whichever is larger.).
3. When the FWD (REV) RUN command is input, operation starts at the lower limit speed without using the UP/DOWN commands.
4. If the JOG command is input while running for an UP/DOWN command, the JOG command has priority.
5. Multi-step speed references 1 to 3 are not effective when an UP/
DOWN command is selected. Multi-step speed references are effective while running in hold status.
6. When 1 is set for the HOLD Output Frequency Memory Selection
(n62), the output frequency can be recorded during HOLD.
Setting Description
0
1
Output frequency is not recorded during
HOLD.
When HOLD status is continued for 5 seconds or longer, the output frequency during HOLD is recorded and the Inverter restarts at the recorded frequency.
Communications/Multi-function Input Terminal Selection
(Setting: 18)
(This function is effective when option card is installed.)
Operation can be changed from communications commands, or from multi-function input terminal or Digital Operator commands.
RUN commands from communications and the frequency reference are effective when the multi-function input terminal for this setting is closed.
RUN commands in LOCAL/REMOTE mode and the frequency reference are effective when the terminal is open.
Using Output Signals (n40)
The functions of multi-function output terminals MA and MB can be changed as necessary by setting constants n40.
• Terminal MA and MB functions: Set to n40
