C-6
C.3. Surge Suppressor
Recommended to install surge suppressor that absorbs surge voltage generated
when the magnetic coil is OFF. This prevents faulty operation or damage to
electronic circuits near the magnetic contactors or switches.
C.4. Magnetic Contactor
A magnetic contactor turns ON and OFF the servo. Be sure to attach a surge
suppressor to the excitation coil of the magnetic contactor.
Select a magnetic contactor based on the current capacity of the FSP amplifier.
For multiply servo systems, select a contactor based on total current capacity.
C.5. Variable Resistor for Speed Setting
A variable resistor provides speed references by applying speed reference voltage
from the external power supply across CN1 pins 1 and 5 as well as 1 and 6.
