4. DESCRIPTION OF PARAMETERS
397
LZE If L (number of hob threads) = 0 is specified at the start of EGB
synchronization:
0 : Synchronization is started, assuming that L = 1 is specified.
1 : Synchronization is not started, assuming that L = 0 is specified.
However, helical gear compensation is performed.
JHD While the C–axis and hob axis are synchronized with each other (in the
G81 mode), jogging and handle feeds around the C–axis are
0 : Disabled
1 : Enabled
DLY Compensating C–axis servo delay with G84 is
0 : Disabled
1 : Enabled

TDP
[Data type] Bit
TDP The specifiable number of teeth, T, of the simple electronic gearbox is:
0 : 1 to 1000
1 : 0.1 to 100 (1/10 of a specified value).
NOTE
In either case, a value from 1 to 1000 can be specified.
ART The retract function executed when an alarm is issued is:
0 : Disabled.
1 : Enabled.
When an alarm is issued, the tool is retracted at the specified feedrate by
the specified amount of travel.
(Parameters Nos. 7750 and 7751)
NOTE
If a servo alarm is issued for an axis along which the tool is
not retracted, servo motor activation is kept until completion
of retraction.
PHS When the G81/G80 block contains no R command:
0 : Acceleration/deceleration is not performed at EGB synchronization
start/cancellation.
1 : Acceleration/deceleration is performed at EGB synchronization
start/cancellation. After acceleration/deceleration at synchronization
start, phase synchronization is automatically performed.
PHD Direction of movement for automatic EGB phase synchronization
0 : Positive (+) direction
1 : Negative (–) direction
