excessive positional deviation alarm (d0) can be reset when the alarm stops and inverter output turns
OFF.
Positional deviation is closely related to positioning frequency and position command gain. When a
certain frequency reference is output at a certain position reference gain, a constant positional devia-
tion is always required. Due to this fact, positional deviation can be improved by either increasing the
detection level of excessive positioning deviation (3037Hex-18Hex, 3037Hex-19Hex) or by increasing
the position control gain (3037Hex-04Hex and 3037Hex-05Hex) when the excessive positional devia-
tion alarm (d0) occurs.

Touch Probe (Latch) Function
This is a function that latches the feedback position when the external latch input signal or the encoder
Z-phase is started.
This function is disabled if neither of “187: EXT1 (External latch input 1)” and “188: EXT2 (External
latch input 2)” is allocated to Input Terminal [DI1] Function Selection (3005Hex-02Hex) and Input T
er-
minal [DI2] Function Selection (3005Hex-03Hex), and if the selection trigger is not encoder Z-phase.
This function is also disabled when bit 0 (Latch function 1) and bit 8 (Latch function 2) of Touch Probe
Function (3052Hex-26Hex) are 0.
