The G-series Servo Drives do not support exponential curve designation fil-
ters. When using a G-series Servo Drive, do not attempt to use an exponential
curve designation filter.
The SMARTSTEP Junior Servo Drives do not support acceleration/decelera-
tion filters and torque limits. When using a SMARTSTEP Junior Servo Drive,
do not attempt to use an acceleration/deceleration curve designation or for-
ward/reverse torque limit designation.
Note (1) For interpolation acceleration and deceleration time settings, the upper
and lower limits for axis acceleration and deceleration speeds are restrict-
ed to a range of 1 to 65,535 [
×
10,000 command units/s
2
]. If the acceler-
ation or deceleration speeds calculated from the linear interpolation
operation settings for an interpolation axis are extremely low or high, the
linear interpolation following may not be correct.
(2) The interpolation acceleration/deceleration times are converted using the
unit for the Second-step Linear Acceleration Constant for W-series Servo
Drives (Pn80B) or Linear Acceleration Constant for G-series Servo
Drives (Pn107) and Second-step Linear Deceleration Constant for W-se-
ries (Pn80E) or Linear Deceleration Constant for G-series Servo Drives
(Pn10A) (10,000 command units/s
2
). In operation, the actual acceleration
and deceleration times are thus affected by the precision of the command
unit.
