Revolution Detection<br />
/TG-ON signal shows that the servo motor is revolving faster than a<br />
certain speed. This signal can be used as a condition to assess the<br />
status of the motor while changing the control mode from the<br />
combination control mode.<br />
Please set the revolution detection level at SEt-16.<br />
The setting range is 1 to 5000 RPM and the default<br />
value is 20.<br />
If the revolution detection level is set too low, a minute revolution can<br />
cause the /TG-ON signal to be displayed.<br />
Speed Limit<br />
To avoid excessive motions in the load, the servo motor can be used<br />
within a limited regular speed.<br />
The speed limit is set by the user at SEt-67. Therefore, the servo drive<br />
operates under the preset limit even if the controller approves a speed<br />
command faster than the set value of the speed limit.<br />
Please set the speed limit method at the third digit<br />
of SET-45.<br />
The set values are as follows.<br />
0: Motor Maximum Speed (default value)<br />
1: SEt-67 Value (RPM)<br />
2: Analog Speed command (Operates in all modes except the speed<br />
control mode)<br />
3: The smaller value between the motor maximum speed and SEt-67<br />
If setting value is bigger than the maximum speed of the motor, speed<br />
is limited to that maximum speed.<br />
Please set the speed limit level at SEt-67.<br />
The setting range is 1 to 5000 RPM and the default<br />
value is 5000.<br />
When the speed limit is set at 1000 RPM, even if the controller<br />
approves a speed command for 1500 RPM, the servo motor operates<br />
at the speed of 1000 RPM. In this case, the signal for speed limit<br />
detection /V-LMT can be allocated, so that the /V-LMT signal can be<br />
displayed when the motor speed is bound by the speed limit.<br />
