Overview

This function block outputs rpm and directional signals based on inputs from an EMD Speed Sensor.
On MC controllers, this function block receives its:

  • Spd input through an MFIn input.
  • DirIn input through either a second MFIn input, a DigAn input, or an AnIn input.

On SC controllers, this function block receives its:

  • Spd input through an MFIn input.
  • DirIn input through either a second MFIn input or through a DigAn input.

See

  • About Function Block Connections on page 8 for an overview of this function block’s connections and signals.

Controller Input Requirements for EMD Function Blocks

  • The following tables list the controller input requirements for the EMD SPD DIR, EMD SPD DIR A, and EMD SPD DIR D function blocks.

EMD_SPD_DIR_A Function Block
Outputs

Function Block Outputs

Item Type Range Description
Status U16 —— Reports the function block’s status.

This function block uses a non-standard bitwise scheme to report its status and faults.

•        0x0000 = Block is OK.

•        0x0008 = Puls/Rev or DirLockHz parameter value is out of range.
Fault U16 —— Reports the function block’s faults.

This function block uses a non-standard bitwise scheme to report its status and faults.

•        0x0000 = Block is OK.

•        0x0001 = Per signal in the function block’s Spd input is too low.

•        0x0002 = Volt/Voltage signal in the function block’s Spd input is out of range.

•        0x0004 = signal in the function block’s Dir input is out of range.
Diag Bus —— Outputs a bus with Freq and FltTmrFreq signals that are available for troubleshooting.
Freq U32 0 to 1,000,

000,000

 The measured frequency of the Speed Sensor. 100,000 = 10,000 Hz.
FaultTmrFreq U16 0 to 65,535 When a frequency fault:

•        Occurs, this output counts up the milliseconds until the function block makes a fault declaration.

•        Clears, the output counts down the milliseconds until the function clears the fault declaration. 1,000 = 1,000 ms.
RPM U16 0 to 2,500 Speed sensor revolutions per minute.

The function block clamps this output at 2,500. 1 = 1 rpm.
dRPM U16 0 to 25,000 Speed sensor revolutions per minute x 10 (deciRPM). The function block clamps this output at 25,000.
Dir S8 -1, 0, +1 The Speed Sensor’s direction of rotation.

•        -1 = Counterclockwise (CCW).

EMD_SPD_DIR_A Function Block
Status and Fault Logic

  • Unlike most other PLUS+1 compliant function blocks, this function block uses non-standard status and fault codes.

Status Logic

Status Hex* Binary Cause Response Correction
A parameter is out of range. 0x0008 1000 Puls/Rev, FaultDetTm, or DirLockHz parameter is out of range. The function block clamps the out-of-range value at either its upper or lower limit. Get the out-of-range parameter back within its range.
  • Bit 16 set to 1 identifies a standard Danfoss status or fault code.

Fault Logic

Fault Hex* Binary Cause Response Delay† Latch‡ Correction
Per signal in the function block’s Spd input is too low. 0x0001 0001 Per signal < 1,250 Hz. The function block outputs its maximum RPM and dRPM values. Y N Check for hardware issues, such as electrical noise, that can produce an invalid per-signal value.
Volt/Voltage signal in the function block’s Spd input is out of range. 0x0002 0010 Volt/Voltage signal is between 1,000 and 2,500 mV

and the block receives no pulses from the Speed Sensor.

 The function block sets its RPM and dRPM outputs to 0. Y N Check for hardware issues, such as electrical noise, that can produce an invalid Volt/ Voltage signal value.
  • Bit 16 set to 1 identifies a standard Danfoss status or fault code.
  • † A delayed fault is reported if the detected fault condition persists for a specified delay time. A delayed fault cannot be cleared until the fault condition remains undetected for the delay time.
  • ‡ The function block maintains a latched fault report until the latch releases.

Function Block Parameters

Item Type Range Description
1. Puls/Rev U8 20–120, 180 Number of pulses per revolution of the Speed Sensor. Refer to the EMD Speed Sensor Technical Information (Danfoss part L1017287) for the correct value.
2. FaultDetTm U16 0–65,535 Sets the time between when the function block detects a:

•       Fault condition and then make a fault declaration.

•        Cleared fault condition and then cleared the fault declaration. 1,000 = 1,000 ms.
3. DirLockHz U16 0–8,000 Sets the frequency above which the function block’s Dir output locks. Above this frequency, the function block does not report changes in direction.

1,000 = 1,000 Hz.
