(2)
Remote Control Station
It allows manual operation control.
(3)
Control equipment
The following control components are available for remote control of the
inverter operation:
• Frequency meter: (Analog display)
• Frequency potentiometer: For setting frequency.
• Frequency POT dial: Precision potentiometer setting indicator dial.
• Drive switch: Runs/stops inverter.
• H-O-A selection switch: For selecting HAND, OFF or AUTO.
5-3 External Options Requiring Partial Adjustment
(1)
Motor Noise Reduction Filter (For TOSVERT-130H only)
An inverter using the PWM control generally causes a higher motor noise
level than experienced with an across the line power source. This filter is
used on 130H (not required on 130H 1)
if
motor noise reduction is required.
By using this option, the noise can be reducedtoa level almost equal to that
of an across the line noise of the motor. Refer to section 4-1-2 for
adjustments.
NOTE: The unit requires a 10% derating of output current for this option.
5-4 External Options Requiring Inverter Modification
(1)
External digital display
This is used to take out the digital indicator (4-digit 7-segment LED) for
displaying frequency/monitor data outside the unit. It can be used at the
maximum distance of 3m (8 feet) from the unit.
(2)
RS232 Serial Communication link with Basic Software.
Used to monitor and limited control of the inverter throught a personal
computer.
(Note) The following options are scheduled to be added:
1) 3-step speed selection
2) 6144f output
3) JOG
4) 81 NARY code input (8 bits)
5) D/A conversion
