Function/Contents
Sets the upper and lower limit values
for viscous friction coefficient estimate
in deterioration diagnosis judgment of
load characteristics estimate after
completion of convergence, when
deterioration diagnosis warning is
valid (Pr6.97 bit 1 = 1).
 When the upper limit value is set at
10000 (max. value), judgment of the
upper limit becomes invalid.
 When the lower limit value is set at 0
(min. value), judgment of the lower
limit becomes invalid.
 If Pr5.73 (upper limit) ≤ Pr5.74 (lower
limit), judgment of both the upper
limit and lower limit becomes invalid.
 The set resolution shall be in units of
0.2%.
Outputs deterioration diagnosis
velocity output (V-DIAG) when the
motor velocity is in the range of
Pr5.75±Pr4.35 (velocity coinciding
width), when deterioration diagnosis
warning is valid (Pr6.97 bit 1 =1)
 Deterioration diagnosis velocity
output has a 10 [r/min] hysteresis.
Sets time required to compute the
torque command average (weighted
frequency) when deterioration
diagnosis warning is valid (Pr6.97 bit 1
= 1) and diagnosis velocity output
(V-DIAG) is ON.
 Time from diagnosis velocity output
(V-DIAG) ON to the start judgment
for upper and lower value of torque
command average value is also a
part of the set time for this
parameter.
 If the setting value is 0, the torque
command average value is not
calculated.
Sets the upper and lower limit values
for torque command average value
when deterioration diagnosis warning
is valid (Pr6.97 bit 1 = 1) and
deterioration diagnosis velocity output
(V-DIAG) is ON
 When the upper limit value is set at
1000 (max. value), judgment of the
upper limit becomes invalid.
 When the lower limit value is set at
-1000 (min. value), judgment of the
lower limit becomes invalid.
 If Pr5.77 (upper limit) ≤ Pr5.78 (lower
limit), judgment of both the upper
limit and lower limit becomes invalid.
