Item Detail specifications
Frequency
setting
Keypad operation: key and key.
Setting with potentiometer (external potentiometer: 1 to 5 kΩ 1/2 W)
Setting with 0 to ± 5 Vdc.
Setting with 0 to ± 10 Vdc.
Setting with 4 to 20 mAdc.
0 to +10 Vdc / 0 to 100% can be switched to +10 to 0 Vdc / 0 to 100% externally.
4 to 20 mAdc / 0 to 100% can be switched to 20 to 4 mAdc / 0 to 100% externally.
(UP/DOWN
control)
An external signal can be used to control the UP or DOWN command.
(Multistep
frequency)
Up to 16 different frequencies can be selected by digital input signals.
(Link operation)
Link operation : RS485 (Standard)
Profibus-DP,Interbus-S,DeviceNet,Modbus Plus,
CAN open (Option)
Acceleration /
deceleration time
(Mode select)
Variable setting in 0.01 to 3600s range. (2 sets of time can be set i
nternally for
each of acceleration and deceleration.)
Linear, S-curve (weak,strong), Non-linear available.
Frequency limiter The high and low frequency limits can be set variably in a 0 to 100% range in Hz.
Bias frequency Can be set variably in -400 to 400 Hz range.
Gain
(frequency setting)
Can be set variably in a 0 to 200% range.
Jump frequency
control
Three jump frequencies and jump width (0 to 30 Hz) can be set.
Rotating motor
pickup
(Flying start)
Operation without shock is possible.
Auto-restart after
momentary
power failure
The motor speed can be detected after power recovery so that the motor is
started at the speed.
Slip
compensation
control
The load during regular operation can be detected for the control of the
frequency. The compe
nsation value can be set variably in a 0.00 to +15.00 Hz
range to the rated frequency.
Droop operation
The load during regular operation can be detected for the control of the
frequency. The compensation value can be set in a -9.9 to 0.0 Hz range to the
rated frequency. (Speed droop characteristics)
Control
Torque limiter
When the load torque in the driving or braking mode exceeds the setting, the
frequency is controlled to control the load torque to an almost constant level.
The limiting torque can be set 20
to 200% and the driving and braking torque
values can be independently set.
The second torque limits can be set.
