5 Precautions for use
−13−
• Use the optional regeneration unit (sold separately) if gravitational operation or other
operation involving up/down movement, or sudden starting/stopping of a large inertial
load, will be repeated frequently.
The factory setting is to use the internal regeneration resistor. Note, however, that the internal regeneration
resistor does not support continuous regenerative operation, gravitational operation or other operations
involving up/down movements, or frequent repeating of sudden starting/stopping of a large inertial load. If
any of these operations must be performed, use the optional regeneration unit (sold separately).
• Note on connecting a power supply whose positive terminal is grounded
The data edit connector (CN4) and analog I/O signals connector (CN6) are not insulated. When grounding the
positive terminal of the power supply, do not connect any equipment (PC, etc.) whose negative terminal is
grounded. Doing so may cause the driver and these equipment to short, damaging both. Use the data setter
OPX-2A to set data, etc.
