2.8 Chopper Braking Resistor
•
SJ Series P1 has a built-in chopper braking circuit in model below.
P1-00044-L (004L) to P1-01240-L (022L)
P1-00041-H (007H) to P1-00930-H (370H)
•
By using an optional braking resistor, permit to use for high
regeneration load application such as lift or high speed load.

•
SJ Series P1 can offer when desired a built-in chopper braking circuit
in models below.
P1-01160-H (450H) to P1-01470-H (550H)
•
Using optional braking unit or regenerative unit, permit to use on
high regenerative load application even for models without built-in
chopp
er braking circuit.
•
The table below shows an example selection of braking resistor to
output 100% of braking torque for each motor rating on list.
