Speed detection level
Unit of data : 0.1%
Valid data range : 0 to 1000
Standard setting value : 30
This parameter sets a speed detection signal (SDTA) detection range.
When the motor speed is (setting data/10)% of a maximum speed or
less, the speed detection signal (SDTA) is set to 1.

Speed zero detection level
Unit of data : 0.01%
Valid data range : 0 to 10000
Standard setting value : 75
This parameter sets a speed zero detection signal (SSTA) detection
range.
When the motor speed is (setting data/100)% of a maximum speed or
less, the speed zero detection signal (SSTA) is set to 1.

Torque limitation value.
Unit of data : 1%
Valid data range : 0 to 100
Standard setting value : 50
This parameter sets a torque limitation value to be applied when the
torque limitation command HIGH (TLMHA) or the torque limitation
command LOW (TLMLA) is specified.
The data indicates limitation values when the maximum torque is
100%.
Torque limitation
command
LOW(TLMLA)
Torque limitation
command
HIGH(TLMHA)
Description
0 0 No torque limitation is imposed.
0 1
The torque is limited to the value
set in this parameter.
1 0
1 1
The torque is limited to a half of
the value set in this parameter.

Load detection level 1
Unit of data : 1%
Valid data range : 0 to 100
Standard setting value : 83
This parameter sets a load detection signal 1 (LDT1A) detection range.
When the output of the spindle motor is (setting data)% of the
maximum output or more, load detection signal 1 (LDT1A) is set to 1.
