• Due to parameter limitations, the “User” access level and all of the associated “A2” parameters are
deleted.
• 3-Wire control is not allowed when the motion software is enabled.
• Parameter b1-01 (Reference Source) is only effective when motion control is disabled (P1-01 = 0).
When motion control is enabled, parameter b1-01 is ignored, and the frequency reference originates
from the motion control routine.
• Parameters d2-02 and d2-03 are disabled, which fixes the minimum output speed at 0%.
• Accel and Decel ramp switching via multifunction digital input or via speed sensing is disabled when a
move is in progress. Accel and Decel ramp switch is controlled by the motion software during a move.
• Encoder direction selection F1-05 is not available when encoder type is “Serial Abs Ch1” (P3-01 = 3).
• PG Channel 2 parameters F1-21 and F1-22 have no effect when motion control is enabled.
• All 230V units will have a default carrier frequency of 2.0 kHz. The maximum carrier frequency setting
on models G7U2075 and smaller is limited to 4.0 kHz.
• The Motion Control algorithm is only available when the drive is in the Flux Vector control method
(A1-02 = 3).
• The distance from home cannot exceed 10
9
encoder counts.
• The 32 bit position monitor registers should be read using a “Read Multiple” Modbus command (03h)
to ensure that the data from high and low words are read together for an accurate reporting of position.
• Using the 32 bit position command, the drive can now operate in a position beyond what the digital
operator can display.
• The drive must be re-homed after a PG Open (PGo) fault occurs.
