MDS-E/EH Series Instruction Manual
4 Setup
#2245 SV045 TRUB
Set the frictional torque when using the collision detection function.
To use load inertia estimation function (drive monitor display), set this parameter, imbalance torque (SV032)
and load inertia display enabling flag (SV035/bitF).
---Setting range---
0 to 255 (Stall current %)
#2246 SV046 FHz2
Set the vibration frequency to suppress when machine vibration occurs.
(Normally, do not set 80 or less.)
Set to "0" when not using.
Related parameters: SV033/bit7-5, SV115
---Setting range---
0 to 5000 (Hz)
#2247 SV047 EC
Set the inductive voltage compensation gain. Standard setting value is "100".
If the current FB peak exceeds the current command peak, lower the gain.
---Setting range---
0 to 200 (%)
#2248 SV048 EMGrt
Input the time required to prevent the vertical axis from dropping by delaying READY OFF until the brake
works at an emergency stop.
Increase in increments of 100ms at a time, find and set the value where the axis does not drop.
When using a motor with a break of HG(-H) Series and HQ-H Series, set to "200ms" as a standard.
When the pull up function is enabled (SV033/bitE=1), the pull up is established during the drop prevention
time.
(Note) When not using the spindle drive unit, use the servo axis that controls vertical axis drop prevention
control to control the power supply (connect with CN4).
Related parameters: SV033/bitE, SV055, SV056
---Setting range---
0 to 20000 (ms)
When set to "0", and the pull up function is enabled (SV033/bitE=1), the alarm "S02 2233 Initial param-
eter error" occurs.
#2249 SV049 PGN1sp
Set the position loop gain during spindle synchronization control (synchronous tapping and synchronization
control with spindle C-axis).
Set the same value as that of the position loop gain for spindle synchronous tapping control.
When performing the SHG control, set this parameter with SV050 (PGN2sp) and SV058 (SHGCsp).
When changing the value, change the value of "#2017 tap_g Axis servo gain".
---Setting range---
1 to 200 (rad/s)
#2250 SV050 PGN2sp
When using SHG control during spindle synchronous control (synchronous tapping and synchronization con-
trol with spindle C-axis), set this parameter with SV049 (PGN1sp) and SV058 (SHGCsp).
Make sure to set the value 8/3 times that of SV049.
When not using the SHG control, set to "0".
---Setting range---
0 to 999 (rad/s)
