Appendix 1 Explanation of Parameters
【#2152】 acc_rate Acceleration rate in proportion to the maximum acceleration rate
Set the rate in proportion to the maximum acceleration rate in rapid traverse.
(Note) If this parameter is set to "0" or "100", constant inclination acceleration/deceleration will be
Acceleration

a
---Setting range---
0 to 100(%)
【#2153】 G0t_rated G0 time constant up to rated speed (multi-step acceleration/deceleration)
Set the acceleration rate up to the rated speed of rapid traverse constant inclination multi-step
acceleration/deceleration.
(Note) If this parameter is set to "0", constant inclination acceleration/deceleration will be applied.
---Setting range---
0 to 4000(ms)
(G0t_rapid) G0 time constant up to rapid traverse speed (multi-step acc./dec.)
Set the acceleration time until the rapid traverse speed of rapid traverse constant inclination multi-
step acceleration/deceleration is applied.
(Note) Set the acceleration time when a pertinent axis is operated independently.
【#2155】 hob_fwd_g Feed forward gain for hobbing machining
Set the feed forward gain when controlling as workpiece axis of tool spindle synchronization II
(hobbing).
---Setting range---
0 to 200 (%)
【#2169】 Man meas rtrn dir Return direction in manual measurement
Select the direction of return operation in manual measurement.
0: Opposite to the contact direction
1: Fixed to the + direction
2: Fixed to the - direction
【#2170】 Lmc1QR Lost motion compensation gain 1 for high-speed retract
Set the lost motion compensation gain in drilling cycle at high-speed retract (CW: - to + direction,
CCW: + to - direction).
Set "-1" when drilling cycle at high-speed retract is not performed.
When set to 0, the performance will follow the setting of "#2171 Lmc2QR (Lost motion compensation
gain 2 for high-speed retract)".
---Setting range---
-1, 0 to 200(%)
