<1> Remove the jumper when installing a DC reactor. Models CIMR-A 2A0110 through 2A0415 and 4A0058 through 4A0675 come with a
built-in DC reactor.
<2> When installing a dynamic braking option, a thermal relay sequence should also be set up to shut off power to the drive in case overheat
occurs.
<3> The drive's protection function for the internal braking transistor needs to be disabled (L8-55 = 0) if using a regen unit such as a regen
converter or some type of dynamic braking options (and therefore not the internal braking transistor). If left enabled, a braking resistor fault
(rF) may result. Make sure Stall Prevention is disabled (L3-04 = 0) whenever using a regenerative converter, a regenerative unit or a dynamic
braking option. If left enabled, the drive may not stop within the specified deceleration time.
<4> Self-cooling motors do not require wiring that would be necessary with motors using a cooling fan.
<5> Supplying power to the control circuit separately from the main circuit requires a 24 V power supply (option).
<6> For control modes that do not use a motor speed feedback signal, PG option card wiring is not necessary.
<7> This figure shows an example of a sequence input to S1 through S8 using a non-powered relay or an NPN transistor. Use jumper S3 to select
sink or source, and an internal or external power supply.
<8> The maximum output current capacity for the +V and -V terminals on the control circuit is 20 mA. Never short terminals +V, -V, and AC, as
this can cause erroneous operation or damage the drive.
<9> Set DIP switch S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.
<10> Enable the termination resistor in the last drive in a MEMOBUS network by setting DIP switch S2 to the ON position.
