Troubleshooting 2 (Servo not ON)
Even though
「
」
is displayed on the setting panel, the servo cannot start.
Table 9.3.2
Cause
What to do
There is no servo ON(SVON) signal input.
Input SVON signal of host control device to the user I/O connector.
Alarm No.15 occurs.
There is no 200V AC input.
Make sure CHARGE LED is ON. If not, check if the 200V AC input
connector(L1/L2) is loosen or the 200V AC is output or not.
Alarm No.15 occurs.
There is no main circuit power input in
multi-axial drive.
Connect the main circuit power supply.
The motor power output connector (U/V/W)
loosen.
Check the connection and make sure it’s OK.
Make sure if it’s connected in accordance with the connector installing
method in the user’s manual.
Drive itself failure.
Consult HCFA Corporation distributor

Troubleshooting 3 (Motor cannot rotate)
The servo is ON, but the motor will not operate.
Table 9.3.3
Cause
What to do
Wrong parameter setting.
For setting all the basic parameters in all control modes, refer to chapter 8
「
Table 8.2.4, Table 8.3.2, Table 8.4.2 and Table 8.5.2
」
.For position control
mode and internal position command mode, refer to
「
Appendix 2 SV-E3
Positioner function
」
.
The connection of user I/O connector is not
correct.
For correct connection, refer to
「
Figure 8.2.1, Figure 8.2.2, Figure 8.2.3,
Figure 8.3.1, Figure8.4.1 and Figure 8.5.1
」
. .For position control mode and
internal position command mode, refer to
「
Appendix 2 SV-E3 Positioner
function
」
.
Command input is restricted.
Disconnect the HOLD and COM- of user I/O connector.
Torque command limit setting is not correct.
Set parameter No.147.0 and 148.0 correctly when using torque command
limit.
CCW/CW drive restriction input becomes
effective.
Set the parameter No.67.0 to
「
0
」
when not using CCW/CW drive
restriction input. CCWL, CWL and COM- of user I/O connector should be
closed when using CCW/CW drive restriction input.
