Appendix B: Serial Communications Considerations
• Motion control software will function with all option card-based serial communications.
• Motion control software will function with the internal Modbus serial communication.
• Reference source (b1-01) should be set to desired reference when motion control is disabled.
• Sequence source (b1-02) should be set to the desired source for run/stop, move, distance select, etc.
• Position Reference Source (P1-02) should be set to the desired source for the position reference.
• Position Reference Source (P1-02) will be overwritten if a digital preset position is selected via
multifunction digital inputs. See Table 1 Profile Selection Information for more details.
• All digital output logic and position monitors are available through serial communications.
• If an option board is required for serial communications (Profibus, Modbus Plus, DeviceNet, Ethernet),
an absolute gray code encoder cannot be used.
• If the learn function is used while serial communications is being employed (even if it is not for control
of the drive), keep in mind that all parameter values written to the drive will be memorized to EEPROM
each time the learn function is activated.
