HIGH STARTING TORQUE OF 200% OR GREATER AT 1HZ
Newly developed technology - Intelligent Sensorless Vector Control - cope provides optimal high torque without motor tuning.
TRIP AVOIDANCE FUNCTION
Advanced over-current trip avoidance function for acceleration, and
over-voltage trip avoidance function for deceleration.
Reduced trip likelihood means improved drive system reliability and
availability.
REMOVABLE CONTROL TERMINAL
Connector type control terminal minimizes control terminal
wiring when performing field maintenance.
Input logic is selectable from Sink or Source to match
external device (PLCs, etc.).
REMOVABLE KEYPAD
Keypad (digital operator) can be connected via a cable.
Remote operation ready.
Three LEDs (power, alarm, run)
on the inverter display drive's status.
OPERATION SOURCE SWITCH
Run command/frequency source are easy to select with a DIP switch.
Default is keypad settings.
Sliding the switch changes the sources to the control terminals.
IMPROVED PID CONTROL
Reverse PID function changes the sign of
the deviation value which is the difference
between target and feedback values.
Upper and lower limits from a target value can be
imposed on the inverter output frequency.
OUTPUT TIMING AND LOGIC FUNCTIONS
Output terminals can be assigned logical operators
AND, OR and XOR with RUN, AL and so on.
ON and OFF delay times are settable for each output
terminal. Allows for more flexible system design.
ANALOG SETPOINT
calculate functions
An offset frequency can be added to or subtracted
from the output frequency when ADD terminal is ON.
For example, if output frequency setting is 40Hz and
offset frequency is 5Hz, output frequency becomes
45Hz (or 35Hz) when ADD terminal is ON.
INTEGRATED EMC FILTER
Reduces electromagnetic noise.
(on European-Version units only)
VERSATILE FUNCTIONS
Pure analog monitor output (8-bit, 0-10V DC)
External thermistor terminal (PTC)
Cooling-fan on/off
Side-by-side installation
Regenerative braking circuit
Instantaneous power failure recovery
Second motor setting
Over-voltage suppression at deceleration
3-wire control
RS-485 Serial port with Modbus®-RTU
Analog input selection
Second acceleration/deceleration setting
Jogging
Auto-carrier frequency reduction
Unattended start protection (USP)
Analog input wire-break detectio
GLOBAL PERFORMANCE
