The following figure shows an example of actual machining program to demonstarete the
meaning of each machine data.
Fig. 14.2 Function of machine data related to acc./dec.
 Spindle
• MD35200 GEAR_STEP_SPEEDCTRL_ACCEL [n] (For each axis)
Meaning: Acceleration under the nth gear speed control
Setting value: [r/sec
2
]
Note: Set this value large enough for spindle load to saturate when the spin-
dle is on acc./dec motion. (If the value is not large enough, when acc./
dec. function is enabled, the motor follows the command so that
SAGR signal will be kept to standstill.
• MD35210 GEAR_STEP_POSCTRL_ACCEL [n] (For each axis)
Meaning: Acceleration under the nth gear position control
Setting value: [re/sec
