14.1.7 Maximum number of motor revolutions
 CNC setting
• MD32250 RATED_OUTVAL [0] (For each axis) ##
Meaning: Ratio of speed reference to maximum number of motor revolutions
Standard setting value: 100 [%]
• MD32260 RATED_VELO [0] (For each axis)
Meaning: Maximum number of motor revolutions
Setting value: To be set to maximum number of motor revolutions (the number of revo-
lutions [min
-1
] under maximum command value)
Assign the value of MD880.
Note: In the case of a Servo drive, the parameter is to be set to specified
maximum number of motor revolutions
×
1.2 (Over-speed alarm
detection speed).
 Drive setting
Settings of Servo axis and Spindle drives in common
• MD880 NORMALIZATION_OVER_PROFIBUS (For each axis)
Meaning: The number of motor revolutions under maximum speed reference
(ox40000000) at PROFIBUS.
Setting value: Setting this parameter is prohibited because it is automatically set to
internal drive data.
CNC creates a value equivalent to MD32260 using this parameter if [min
-
1
] and MD32250 = 0.
Servo drive
No related parameter exists. Maximum number of motor revolutions is automatically read
from a motor encoder and set. The setting value multiplied by 1.2 is displayed at MD880.
Spindle drive
• MD6500 (Cn500) RATED_SPEED_SETTING (For each axis)
Meaning: Rated speed
Setting value: [min
-1
]
The value of this parameter is also displayed at MD880.
