*1. Connect OMRON Power Cables to the motor connection terminals. For R88A-CA1□□ of the power cable
manufactured by OMRON, the wire at rated temperature of 85° is used. In some cases, the wire does not ful-
fill its size described in the motor terminal block. It does not affect the operation.
*2. Use the wire with the same current capacity for the wiring of the motor connection terminals and for that of B1
and B2. Refer to Specifications of External Regeneration Resistors and External Regeneration Resistance
Units on page 3-127 for the wire size when the external regeneration resistor and the external regeneration
resistance unit (both manufactured by OMRON) are used.
