5 PARAMETERS FOR POSITIONING CONTROL
5.3.1 Relationships between the speed limit value, acceleration time, deceleration time and
rapid stop deceleration time
According to the G-code instructions, there are two different acceleration/deceleration
modes, acceleration-fixed acceleration/deceleration and time-fixed
acceleration/deceleration.
(1) Acceleration-fixed acceleration/deceleration system
(a) G01, G02, G03, G12, G13 or G32 during G101 execution
The acceleration/deceleration mode of acceleration-fixed
acceleration/deceleration is used.
The actual acceleration time, deceleration time and rapid stop deceleration
time are shorter than their settings as the positioning speed is lower than
the speed limit value.
The setting ranges of acceleration time, deceleration time and rapid stop
deceleration time is 1 to 65535[ms].
(b) G00 (without M-code), G28 (high-speed home position return),
G30, G53 or G00 including M-code during G101 execution
The acceleration/deceleration mode of acceleration-fixed
acceleration/deceleration is used.
The calculation of acceleration for acceleration/deceleration is based on the
lower speed among the feed speed (Refer to Section 5.2.5) from high-
speed feed rate of fixed parameter and the speed limit value of parameter
block.
At the override of 100[%], the real acceleration time, real rapid stop
deceleration time and real deceleration time are equal to their settings.
The setting ranges of the acceleration time, deceleration time and rapid
stop deceleration time are 1 to 65535[ms].
(2) Time-fixed acceleration/deceleration system
(a) G00 including M-code during G100 execution (default), G01,
G02, G03, G12, G13 or G32
The acceleration/deceleration mode of time-fixed acceleration/deceleration
is used.
The preset acceleration time is used to perform acceleration, deceleration
or rapid stop deceleration processing.
The setting range of the acceleration time is 1 to 5000[ms].
If the setting exceeds 5000[ms], the acceleration time is clamped at
5000[ms].
At this time, an error does not occur.
