【#3120】 staptr Time constant reduction rate in high-speed synchronous tapping
When performing high-speed synchronous tapping control(#1281/bit5), set the reduction rate of the
time constant compared to the time constant in normal synchronous tapping.
(Setting "0" or "100" will be regarded as reduction rate zero, so the time constant won't be reduced.)
E.g.) When set to "10", time constant in high-speed synchronous tapping will be 90% of that in
normal synchronous.
---Setting range---
0 to 100(%)
(Note) The inclination of linear acceleration/deceleration control for multi-step synchronous tapping is determined by the
ratio of "rotation speed" to "acceleration/deceleration time constant". When using multi-step synchronous tapping,
the inclination should be set so that the 1st step is higher than the second step, and the second step is higher than
the third step. When the inclination of the latter step is higher, the multi-step setting is disabled and the inclination of
the former step is applied.

【#2232】 SV032 TOF Torque offset
Set the unbalance torque on vertical axis and inclined axis.
When the vertical axis pull up function is enabled, the pull up compensation direction is determined
by this parameter's sign.
When set to "0", and the pull up function is enabled (SV033/bitE=1), the alarm "S02 2233 Initial
parameter error" occurs.
This can be used for speed loop delay compensation and collision detection function.
To use load inertia estimation function (drive monitor display), set this parameter, friction torque
(SV045) and load inertia display enabling flag (SV035/bitF).
---Setting range---
-100 to 100 (Stall current %)
【#2237】 SV037 JL Load inertia scale
Set the motor axis conversion total load inertia including motor itself in proportion to the motor
inertia.
SV037(JL)=(Jm+Jl)÷Jm×100
Jm: Motor inertia
Jl: Motor axis conversion load inertia
For linear motor, set the gross mass of the moving sections in kg unit.
<<Drive monitor load inertia ratio display>>
Set SV035/bitF=1 and imbalance torque and friction torque to both SV032 and SV045, and then
repeat acceleration/deceleration for several times.
---Setting range---
For general motor: 0 to 5000 (%)
【#2313】 SV113 SSF8 Servo function 8
Select the servo functions.
bit 7 : nmerc Machine error compensation amount
(Note) Do not turn ON the NC power supply with the setting as disable (set to "1"). The initial
parameter error alarm is detected.
0:Enable (Normal setting)
1:Disable
For linear motor: 0 to 5000 (kg)
