Programming Parameters
5-40
Bit 6 – Disable Field Loss Detection: When set, this bit will disable
the check for field loss. This feature could be used in applications
where external field supplies or permanent magnet motors are used.
When clear, field loss detection is active. Caution should be used
when disabling the Field Loss Detection feature. Damage to
equipment or injury to personnel could occur during an undetected
field loss with non-permanent magnet type motors.
Bit 7 – No Flux Compensation: When set, the torque command will
not be divided by Flux to Produce the Armature Current Command.
As a result, the flux will be treated as 100%, even if the field is
weakened. If bit 7 is set to 0, the torque command will be divided by
flux to produce the armature current command.
Parameter 628 – Process Trim Select [Proc Trim Select]
Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 3
Default Value: 0
Description: This is a word of data containing one of two selections
for applying the output of the process trim regulator. Possible
selections are:
0 = Do not use process trim output
1 = Trim velocity reference
2 = Trim torque reference
3 = Trim Velocity with Ramp Stop
Parameter 629 – Motor Overload Select [Mtr Overload Sel]
Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 4
Default Value: 1
Description: This parameter specifies a selection of motor overload
characteristics:
0 = Overload function disabled
1 = 60 seconds to trip at 150% armature current for externally cooled
motors.
2 = 60 seconds to trip at 200% armature current for externally cooled
motors.
3 = 60 seconds to trip at 150% armature current for self cooled
motors.
4 = 60 seconds to trip at 200% armature current for self cooled
motors.
