Trial Operation In Speed Control - YASKAWA JUSP-MD D01A Series User Manual

4 Trial Operation

4.3.2 Trial Operation in Speed Control

(1) Connecting a Safety Function Device
Connect a safety function device using the following procedure.
1.
Remove the safety function's jumper connector from CN8.
2.
Connect a safety function device to CN8.
Note: When not using the safety function, use the SERVOPACK with the safety function's 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 servomotor and no torque will be output. In this case, the multi-wind-
ing drive unit and SERVOPACKs will enter a hard wire base block state.

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.

Recheck the power supply and the input signal circuits, and turn ON the control
power supply to the multi-winding drive system.
Adjust the speed reference input gain (Pn300).
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.
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.
Note: The factory setting is 6 V at the rated speed.
Check the speed reference value using the monitor display (Un001).
Check the motor rotating speed using the monitor display (Un000).
Check that the values in step 6 and step 7 (Un001 and Un000) are equal to each other.
Check the motor rotation direction.
Note: To switch the motor rotation direction without changing the polarity of the
analog speed reference, refer to 5.2.2 Servomotor Rotation Direction
Return the speed reference input to 0 V.
Turn OFF the servo ON signal (/S-ON).
Hold the jumper connector with
two fingers and pull it out.
