The Diagnostics menu allows the user to monitor the operation of the drive. Diagnostics that can be monitored are
described in the following paragraphs. These diagnostics are read-only.
TOTAL SPD.DMD.
Speed loop total setpoint after the ramp-to-zero block.
SPEED FB UNFIL
Raw speed feedback, usually used for analogue outputs.
SPEED FEEDBACK
Speed loop feedback.
SPEED ERROR
Speed loop error.
TORQUE DEMAND
Current loop demand (speed error PI output or external current demand
clamped by all the current limits).
TORQUE FEEDBACK
Scaled and filtered torque.
CURRENT FEEDBACK
Scaled and filtered current.
TERMINAL VOLTS
Scaled motor output volts.
DC LINK VOLTS
DC link volts.
TERM V INTEGRAL
Output out motor volts compensation loop..
ACTUAL POS I LIM
Overall positive current limit value.
ACTUAL NEG I LIM
Overall negative current limit value.
INVERSE TIME O/P
Inverse time clamp output level.
AT CURRENT LIMIT
Current demand is being restrained by the overall current limit.
AT ZERO SPEED
At zero speed feedback.
AT ZERO SETPOINT
At zero speed demand.
AT STANDSTILL
"
AT ZERO SPEED
" and "
AT ZERO SETPOINT
".
STALL TRIP
Armature current is above "
STALL THRESHOLD
"
and "
AT ZERO SPEED
"
but not "
AT ZERO SETPOINT
".
RAMPING
If the difference between the ramp input and the ramp output is greater than the
"
RAMP THRESHOLD"
, then "
RAMPING
" is
TRUE
.
DRIVE START
Controller start / run command.
DRIVE ENABLE
Drive speed and current loop are enabled / quenched.
OPERATING MODE
Indicates whether the drive is in RUN, JOG 1....STOP etc.
HEALTHY
HEALTH OUTPUT
READY
RUN
CO-PRO PRESENT
Indicates that there is a co-processor fitted and working normally, only
applicable to the 620L and 620Adv.
