releasing mechanical brake. If the dwell time is
set at ‘0’, this function is not available. In dwell
operation, the inverter outputs AC voltage not a
DC voltage.
☞
Note: DC Injection Braking does not output torque to an
intended direction. It is just to hold the motor.
[Dwell Operation]
FU2-10 ~ FU2-16: Frequency Jump
To prevent undesirable resonance and vibration
on the structure of the machine, this function locks
out the potential resonance frequency from
occurring. Three different jump frequency ranges
may be set. This avoidance of frequencies does
not occur during accelerating or decelerating. It
only occurs during continuous operation.
[Frequency Jump]
☞
Note: When the reference frequency is set inside the jump
frequency, the output frequency goes to the frequency marked
by “
n
” symbol.
☞
Note: If one frequency jump range is required, set all ranges to
the same range.
FU2-19: Input/Output Phase Loss Protection (Bit
Set)
This function is used to cut the inverter output off
in case of phase loss in either input power or
inverter output.
