7. User Interface
Terminal block to connect external devices for remote control or monitoring power
supply is located on the left lower inside of front door.
Terminals for I/O signals.
7.1.1. Analog signal input (TB1)
R+5V: 5V reference: This 5V reference voltage is available for connecting to a
potentiometer remotely. Terminal R+5V to top of the pot, terminal P-DEMD to
the wiper and terminal GND (ground) to the bottom of the pot.
P-DEMD: The voltage level at this terminal controls the command reference. 0
volts is minimum, and 5 volts is maximum. A PLC can be connected to this
terminal with its reference to GND. This terminal applies to the power control
mode “EXT 0-5V or EXT4-20mA”, and SW2 must be set as same mode.
GND; Common terminal for input signals (ground).
7.1.2. Analog signal output (TB1)
M-FRQ; Frequency monitoring signal (0~440V, 4.4V = 440kHz).
GND; Common terminal for input signals (ground).
M-PWR: Output power monitoring signal (0~5V, 100%=5V).
