8.2 Common Specifications
Item Description Remarks
Control system
Vector control with PG (for an asynchronous motor)
Vector control with PG (for a synchronous motor)
Torque vector control (Open loop control for an asynchronous motor)
*1)
Speed control
Max. speed
120 Hz (3600 r/min for 4-pole motor) in the equivalent frequency
Pulse encoder frequency: 100 kHz max.
15 kHz or more recommended at the maximum speed
Controllable
range
0 to 120 Hz (0 to 3600 r/min for 4 pole motor) in the equivalent frequency
Control
accuracy
Analog setting: ±0.2% of max. speed (ambient temp. within 25 ±10°C)
Multistep speed command/via-communications command:
±0.01% of max. speed (ambient temp. within -10 to +50°C)
Setting
resolution
Analog setting: 1/1000 of max. speed
Multistep speed command: 0.01 Hz in the equivalent inverter output frequency
(99.99 Hz or less), 0.1 Hz (100.0 to 120.0 Hz)
Via-communications command: 1/20000 at the max. speed or 0.01 Hz (fixed) in
the equivalent inverter output frequency
Control facility
Start/stop
Terminal command: Run forward/reverse, coast-to-stop, external alarm, reset
alarm, etc.
Link operation: Operation by RS485 or CAN bus communications link
Key operation: Start and stop with
/
/
keys.
Note Before to proceed to running with these keys switch the mode from Remote
to Local using the multi-function keypad.
Carrier
frequency
Data: Variable within 5 to 16 kHz
Note The carrier frequency may drop automatically according to the ambient
temperature or output current to protect the inverter. This protective operation
can be canceled by function code H98.
Speed
command
Multistep speed command source: Combination of 3 terminal command (8 steps)
Analog input
Can be set with external voltage/current input.
• 0 to ±10 VDC/0 to ±100% (terminal [12], [V2])
• 4 to 20 mA DC/0 to 100% (terminal [C1])
Link operation: Available for RS485 and CAN bus communications link.
Key operation: Can be set with / keys.
Note Before to proceed to running with these keys switch the mode from Remote
to Local using the multi-function keypad.
