Trial Operation In Speed Control - YASKAWA SGMJV User Manual

3.
Connect a safety device to CN8.
Note: When not using the safety function, use the SERVOPACK with the safety function jumper connector (JZSP-
CVH05-E provided as an accessory) inserted in CN8. If the SERVOPACK is used without the jumper connector
inserted into CN8, no current will flow to the motor and no torque will be output. In this case, "Hbb" will be dis-
played on the Panel Operator or the Digital Operator.

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 4.3.1Inspecting Connection and
Status of Input Signal Circuits.
Step
Recheck the power supply and the input signal circuits, and turn ON the control
1
power supply.
2
Adjust the speed reference input gain (Pn300).
3
Turn ON the main circuit power supply.
Check that speed reference input (the voltage between V-REF and SG) is 0V, 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 for 6 V at the rated speed.
6 Check the speed reference value in monitor mode (Un001).
7 Check the motor speed in monitor mode (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 (/S_ON) signal.
