Design and Installation
j Setup Method
Perform the following procedure carefully. Mistakes may lead to errors in the setup.
1. Wire the Position Driver, Servomotor, and encoder correctly if they are not already wired correctly.
2. Connect the battery.
3. Turn ON power to the Position Driver.
4. Leave the power ON for three minutes.
Note An alarm may be generated, but it can be cleared with the following procedure.
5. Perform the following steps for 30-W to 750-W models.
a) Turn OFF the power to the Position Driver.
b) Remove the encoder connector.
c) Reset the data by shorting between encoder connector terminals 13 and 14 (on the motor side)
for one or two seconds. (See the following diagram.)
6. Perform the following steps for 1-kW to 2-kW models.
a) Turn OFF the power to the Position Driver.
b) Remove the encoder connector.
c) Reset the data by shorting between encoder connector terminals R and S (on the motor side) for
two minutes. (See the above diagram.)
d) Remove the short between R and S.
e) Confirm that the voltage between R and S is 0.4 V or less. The S terminal is ground.
f) If the voltage is greater than 0.4 V, reconnect the terminals until the voltage drops to 0.4 V or less.
7. Restore the wiring to its original state.
8. Turn the power back ON to the Position Driver.
9. If no error occurs, the setup has been completed.
10. If an alarm (A.L41, 42 or 43) occurs, repeat this procedure from the beginning.
