SED2 VFD Operation & Maintenance Manual NOTES: 1. The ON and the consecutive OFF1 command must have the same source. 2. If the ON/OFF1 command is set for more than one digital input, only the last set digital input is valid; for example, DIN3 is enabled. OFF2 This command causes a free coasting of the motor to standstill (impulses for the power section of the SED2 are disabled). NOTE: The OFF2 command may have one or several sources. By default, the OFF2 command source is set to BOP/AOP.

Chapter 9 – SED2 Communications Chapter 9 — SED2 Communications Overview The SED2 drives are a family of inverters that are built, sold, and serviced by Siemens Building Technologies, Inc.- Adjustable Frequency Drives Group (SBT-Drives). Siemens Building Technologies has a Protocol 1 (P1) communication driver, FLN connection, and point database that is built into their drives and allows them to coexist on an APOGEE network with other floor level network (FLN) devices.
PAGE 100
SED2 VFD Operation & Maintenance Manual RS-232 and RS-485 Serial Interfaces Serial communications use carefully defined hardware and software protocols. The software protocol defines the baud rate, word length, and meaning of the signal, and can be defined by designers for their particular needs. Standards can also be specially developed, but most users adopt an existing standard. Typical standards are RS-232 and RS-485. These standards define voltages, impedance, etc. but not the software protocol.

Chapter 9 – SED2 Communications • Check the drive address. All drives on a bus must have unique addresses, even if they are in local control. The drives will always reply to a valid message, even if serial control is not enabled.

Chapter 9 – SED2 Communications Strategies for FLN (P1) Monitoring – Several SED2 parameters are available for monitoring purposes. These include both binary and analog data.
PAGE 104
SED2 VFD Operation & Maintenance Manual When using this strategy, the point to unbundle and command for the setpoint is FREQ REF (Point 51). FREQ REF (Point 51) has a slope of 0.006103516, which corresponds to a value of 16384 (4000h)=100%. Unbundle PI FEEDBACK (Point 60) to monitor the control variable (water temperature). These points are provided with units of percent, where 0% and 100% correspond to the range of the sensor that measures the control variable.
PAGE 105
Chapter 9 – SED2 Communications Slaving the Drive CAUTION: This strategy is not normally recommended because you are using the network communications to close the loop. Delays due to network traffic can cause control to be degraded or lost, and depending on the setup of the drive, if there is a problem with the network, the drive may cause physical damage to the HVAC system by winding up to its maximum or dropping off to its minimum speed.

SED2 VFD Operation & Maintenance Manual Digital Inputs – Use DIGITAL IN 1 through DIGITAL IN 6 (Points 71 through 76) to monitor the status of the SED2 digital inputs from the field panel. This is useful when the SED2 is programmed for control of drive functions (start/stop, fault reset, off, etc.) via the SED2 control terminal strip. Over the P1 serial link, you can monitor a control sequence that requires receipt of a contact closure on the SED2 terminal strip.

Appendix A: Parameter Reference List Dependency: If P term=0, I term acts on the square of the error signal. Note: If the system is prone to sudden step changes in the feedback signal, P term should normally be set to a small value (0.5) with a faster I term for optimum performance. The D term (P2274) multiplies the difference between the present and previous feedback signal thus accelerating the controller reaction to an error that appears suddenly.

Appendix C: Electrical Installation Motor cables should be as short as possible and should not exceed 82 ft (25 m). Connect the neutral conductor of all motors controlled by a SED2 drive directly to the ground connection (PE) of the respective SED2. • Use ribbon cables, as they have lower impedance at high frequencies. • Check that the contactors in the control cabinet are suppressed, either with RC circuits for AC contactors or flywheel diodes for DC contactors.

SED2 Operation & Maintenance Manual Addendum Appendix E: BiCo (Binector and Connector) Data Set Functions Introduction The SED2 provides user access levels, set by parameter P0003. User access level 1 gives access to the most frequently used parameters. User access level 2 gives access to more advanced parameters. For example, P0701 sets the function of Digital Input 1 with possible values such as: 1=ON right 12=Reverse 15=Fixed frequency, etc .
PAGE 201
Appendix E: BiCo Data Set Functions NOTE: If P0701, P0702, P0703 or P0704 are set to 99, it is not possible to change them to another value and the drive must be reset to factory defaults. 1. Since digital input 2 is "open" to BiCo settings, a new value of 722.1 now appears in P0731. The value 722.1 means "connect to digital input 2" (722.0 = connect to digital input 1, 722.2 = connect to digital input 3, etc.). Set P0731 to 722.1. 2. Run the SED2 using input 1 and operate the value using input 2.

SED2 Operation & Maintenance Manual Addendum 3. Define the source of the fixed frequencies by setting P1020=722.0, P1021=722.1, P1022=722.2. (This defines the source of each frequency as digital input 1, 2, and 3.) 4. Define the mode of operation by setting P1016, P1017, P1018 = 2. (This sets the mode of operation of fixed frequencies to 'select fixed frequency and ON right command'. 5. Select JOG ramp times instead of normal ramp times by setting P1124 = 722.2.
