4_ECZ Home ELevel
Range : 0~1
Unit : LOGIC VOLTAGE LEVEL
Authority : Super Admin
Default : 0
Effective time : Instant
Note : When this parameter is enabled, encoder Z phase positioning of
corresponding axis will be enabled automatically in mechanical home
mode, i.e. the “servo home” positioning; in this mode, the accuracy of
repeated home positioning depends on servo positioning accuracy, and
therefore it is recommended to enable this function for servo motor.
Step motor doesn’t have encoder and can’t enable this option, or else
the signals can’t be scanned during mechanical home operation and will
move constantly.

Note : Hard limit has two modes, i.e. hardware response and software
scanning;
Hardware response mode is integrated by the motion chip, and is
triggered by the effective voltage level of the circuit test limit pin.
Therefore, it is highly real ‐ time, but it also has a defect. If the external
interference is serious, the normal pulse will be affected and the system
doesn’t alarm because it can’t read the error state in time, which will
cause loss; therefore, this function requires that the wiring switch uses
normally closed connection, i.e. high effective level; this function
considers the complexity of field environment and the default value is
off.
Scanning mode is integrated by the system and can’t be shielded. The
scanning mode inputs signal by accessing specified function number and
uses software anti ‐ interference detection technology to check whether
limit alarm occurs or has no interference. This requires certain time to
check, and thus the real time isn’t as well as interrupted limit. However,
