3087 4087 4087
Excessive speed level
Unit of data : 1%
Valid data range : 0 to 115
Standard setting value : 115
This parameter sets an excessive speed level.
When the speed exceeds [maximum motor speed (No. 4020) × setting
data (%)], the excessive speed alarm (SPM alarm 07) is issued.
WARNING
Make sure this parameter is set to the standard
setting value. Do not change the value.

3088 4088 4088
Velocity error excess detection level when the motor is bound
Unit of data : 0.01%
Valid data range : 0 to 10000
Standard setting value : 75
This parameter sets a velocity error excess (SPM alarm 31) detection
level when the motor is bound.
If a velocity error equal to or greater than [maximum motor speed (No.
4020) × setting data (%)] occurs when the motor is bound, for
example, the motor binding alarm (SPM alarm 31) is issued.

3089 4089 4089
Velocity error excess detection level when the motor is rotating
Unit of data : 0.1%
Valid data range : 0 to 1000
Standard setting value : 200
This parameter sets a velocity error excess detection level when the
motor is rotating.
If a velocity error equal to or greater than [maximum motor speed (No.
4020) × setting data (%)] occurs, the velocity error excess alarm (SPM
alarm 02) is issued.

3090 4090 4090
Overload detection level
Unit of data : 1%
Valid data range : 0 to 100
Standard setting value : 90
This parameter sets a condition for detecting the short-time overload
alarm (spindle alarm 29).
If the state where a load equal to or greater than setting data (%)
(maximum motor output [load meter full scale] = 100%) is imposed
on the spindle motor lasts for a specified period (set in No. 4123) or
more, the short-time overload alarm (SPM alarm 29) is issued.
