d2-03: Master Speed Reference Lower Limit
n
Unlike frequency reference lower limit (d2-02) which will affect the frequency reference no matter where it is sourced from
(i.e., analog input, preset speed, Jog speed, etc.), the master speed lower limit (d2-03) sets a lower limit that will only affect
the analog input (terminals A1 and A2) that is the active master speed frequency.
Set as a percentage of the maximum output frequency.
Note: The lower limits for the Jog frequency, multi-step speed settings, and 2-step speed settings do not change. When lower limits are set to both
the frequency reference (d2-02) and the main frequency reference (d2-03), the drive uses the greater of those two values as the lower limit.
No.
d2-03
E2-01: Motor Rated Current
n
Provides motor control, protects the motor, and calculates torque limits. Set E2-01 to the full load amps (FLA) stamped on
the motor nameplate. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E2-01.
No.
E2-01
<1> Display is in the following units:
BV0006 to BV0018, 2V0006 to 2V0040, and 4V0002 to 4V0023: 0.01 A units.
2V0056 to 2V0069 and 4V0031 to 4V0038: 0.1 A units.
Note: An oPE02 error will occur if the motor rated current in E2-01 is set lower than the motor no-load current in E2-03. Set E2-03 correctly to
prevent this error.
d3: Jump Frequency
u
d3-01 to d3-04: Jump Frequencies 1, 2, 3, and Jump Frequency Width
n
In order to avoid continuous operation at a speed that causes resonance in driven machinery, the drive can be programmed
with three separate Jump frequencies that will not allow continued operation within specific frequency ranges. If the speed
reference falls within a Jump frequency dead band, the drive will clamp the frequency reference just below the dead band and
only accelerate past it when the frequency reference rises above the upper end of the dead band.
Setting parameters d3-01 through d3-03 to 0.0 Hz disables the Jump frequency function.
No.
