13-6 GV6000 AC Drive User Manual
• Float Capability (ability to hold full torque at zero speed)
• Micro-Positioning
• Fast Stop
• Speed Deviation Fault, Output Phase Loss Fault, Encoder Loss Fault.
Encoderless Torque Proving functionality includes:
• Torque Proving (includes flux up and last torque measurement)
• Brake Proving
• Micro-Positioning
• Fast Stop
• Speed Deviation Fault, Output Phase Loss Fault.
Important: Brake Slip detection and Float capability (ability to hold load at zero
speed) are not available in encoderless Torque Proving.
!
ATTENTION:Loss of control in suspended load applications can cause
personal injury and/or equipment damage. Loads must always be
controlled by the drive or a mechanical brake. Parameters 600-612 are
designed for lifting/torque proving applications. It is the responsibility
of the engineer and/or end user to configure drive parameters, test any
lifting functionality and meet safety requirements in accordance with all
applicable codes and standards.
!
ATTENTION:User must read the following prior to the use of Torque
Proving with no
encoder.
ATTENTION:Encoderless Torque Proving must be limited to lifting
applications where personal safety is not a concern. Encoders offer
additional protection and must be used where personal safety is a
concern. Encoderless Torque Proving can not hold a load at zero speed
without a mechanical brake and does not offer additional protection if
the brake slips/fails. Loss of control in suspended load applications can
cause personal injury and/or equipment damage.
ATTENTION:It is the responsibility of the engineer and/or user to
configure drive parameters, test any lifting functionality and meet safety
requirements in accordance with all applicable codes and standards.
If encoderless Torque Proving is desired, the user must certify the
safety of the application. To acknowledge that the end user has read
this “Attention” and properly certified their encoderless application, bit
8 (“TPEncdless”) of Compensation (56), must be changed to a “1.”
This will disable Fault 28, “See Manual” and allow bit 1 of Parameter
600 to be changed to a “1” enabling encoderless Torque Proving.
