Trial Operation In Speed Control - YASKAWA Sigma-V Series User Manual

4.3.2 Trial Operation in Speed Control

Perform the following steps for trial operation in speed control. The steps are specified on the condition that
input signal wiring for the speed control has been completed according to 4.3.1 Inspecting Connection and
Status of Input Signals.
Step
Recheck the power supply and the input signal circuits, and turn ON the control
1
power supply of the SERVOPACK and converter.
2 Adjust the speed reference input gain (Pn300).
3 Turn ON the main circuit power supply of the SERVOPACK and converter.
Check that speed reference input (the voltage between V-REF and SG) is 0 V, and
turn ON the servo ON (/S-ON) input signal.
4
Note: If the servomotor rotates at a very low speed with the speed reference input at
0 V, adjust the reference offset so that the servomotor will not rotate.
Gradually increase the voltage of the speed reference input (i.e., the voltage between
V-REF and SG) from 0 V.
5
Note: The factory setting is 6 V at the rated speed.
6
Check the speed reference value using the monitor display (Un001).
7
Check the motor rotating speed using the monitor display (Un000).
8 Check that the values in step 6 and step 7 (Un001 and Un000) are equal to each other.
Check the motor rotation direction.
9
Note: To switch the motor rotation direction without changing the polarity of the
analog speed reference, refer to 5.2.2 Servomotor Rotation Direction
10 Return the speed reference input to 0 V.
11 Turn OFF the servo ON signal (/S-ON).
