  • Page 4: Important Information

    The word "drive" as used in this manual refers to the controller portion of the adjustable speed drive as defined by NEC. Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel.

    - Measure the voltage of the DC bus between the PA/+ and PC/– terminals to ensure that the voltage is less than 42 Vdc. - If the DC bus capacitors do not discharge completely, contact your local BLEMO representative. Do not repair or operate the drive •...
  • Page 6: Documentation Structure

    Documentation structure The following ER23 technical documents are available on the BLEMO website (www.blemo.com). Installation manual This manual describes how to install and wire the drive. Programming manual This manual describes the functions, parameters and use of the drive terminal (integrated display terminal, optional graphic display terminal and optional remote terminal).
  • Page 7: Presentation

    Presentation The ER23 can be connected directly to Modbus and CANopen buses by means of an RJ45 connector, which supports both protocols. The communication function provides access to the drive’s configuration, adjustment, control and monitoring functions. The "Communication variables" User's Manual defines the drive control processes and the drive variables which can be accessed by these buses.

  • Page 9: Communication Bus Monitoring

    Communication bus monitoring In the event of loss of communication the drive behaviour can be configured via the "SLL" or "COL" parameters (page 53). This configuration is saved if the power supply is disconnected. In its factory setting, loss of communication triggers a detected fault (COF, CNF, SLF) with freewheel stopping.

    Function compatibility Incompatible functions The following function will be inaccessible or deactivated in the cases described below: Catch on the fly This is only possible for 2-wire level detection control (tCC = 2C and tCt = LEL or PFO). This function is locked if automatic injection on stopping is configured as DC (AdC = Ct). Function compatibility table The choice of application functions may be limited by the number of I/O and by the fact that some functions are incompatible with one another.

  • Page 57: Replacing An Er22 With An Er23

    If necessary, it is easy to replace an ER22 with a ER23 in an installation communicating via Modbus. In fact, most of the variables used in the ER22 are found in the ER23 with the same addresses (double addressing). • To replace an ER22, the ER22 addresses in this table can be used, but only these. All the other ER22 addresses must be replaced with those for the ER23.
