<1> Remove the jumper when installing a DC reactor. Models CIMR-A2A0110 through 2A0415 and 4A0058 through 4A1200 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> Supplying power to the control circuit separately from the main circuit requires a 24 V power supply (option).
<5> This figure shows an example of a sequence input to S1 through S8 using a non-powered relay or an NPN transistor. Install the wire link
between terminals SC-SP for Sink mode and SC-SN for Source mode. Leave it out for external power supply. Never short terminals SP and
SN as doing so will damage the drive. (see Sinking/Sourcing Mode for Digital Inputs on page 88)
<6> The maximum current supplied by this voltage source is 150 mA if no digital input option card DI-A3 is used.
