bit 18 Commanded Velocity Exceeds
TASX
Bit 18 is set when the velocity demand from the internal Gem6K control loops exceeds the
limits set by the
the "Override Mode," in which the drive software clamps the maximum allowable velocity
command to the value set by
drive in all operating modes (
bit 19 Bridge is in Foldback Mode (GV6K only):
TASX
When a GV6K drive produces more than its rated continuous current, a software algorithm
determines on an ongoing basis the amount of power being delivered by the drive to the
motor. When this value exceeds the safe threshold for the drive, the drive either goes into
Foldback Mode or faults, depending on the
the limits of the drive's capabilities, the drive might go into Foldback Mode for a short period
of time. Bit 19 stays latched, however, so that the user can determine that foldback occurred.
bit 20 Power Dissipation Circuit Active (GV6K and GT6K):
TASX
When a Gem6K drive attempts to slow a motor down, the stored energy in the motor and load
must be absorbed by the drive. This regenerative energy will increase the bus voltage in the
drive until either a regenerative power dissipation circuit dissipates the energy or a drive over-
voltage fault (reported in
and GV6K-H40, internal regenerative power dissipation circuitry is provided to dissipate this
energy; when this circuitry is activated,
GV6K-U6, and GV6K-U12 drives, the external 'Gemini Power Dissipation Module' or
'GPDM' option can be used to dissipate this energy —
drives.
