<CHNGDYN> Block Fault Condition

The following table outlines several situations that may cause an error, and will turn on

the blocks “Error” output bit. The block “Error” output will cleared if the EXECUTE bit

goes low, but the Error ID (MW3**81 and MW3**82) will remain in the RDA. To reset

the Error ID, use the Alarm Reset Function Block.

Note that each axis has its own Error ID stored in its RDA axis section, offset by 200 for

each axis. Example: Axis#1 stores to MW30181, Axis #2 stores to MW30381, etc.

Internal Fault Bit Cause Note

JerkOut

AB000001

S-curve value is

not within

acceptable

range.

Bit must be on or error will occur. Sets

RDA Error ID (MW3**81) bit 3 on if

error state exists.

AccelOut

AB000002

Acceleration

value is not

within acceptable

range.

Bit must be on or error will occur. Sets

RDA Error ID (MW3**81) bit 3 on if

error state exists.

DecelOut

AB000003

Deceleration

value is not

within acceptable

range

Bit must be on or error will occur. Sets

RDA Error ID (MW3**81) bit 3 on if

error state exists.

VelOut

AB000004

Speed value is

not within

acceptable

range.

Bit must be on or error will occur. Sets

RDA Error ID (MW3**81) bit 3 on if

error state exists.

axisInErr

AB000005

The axis number

entered on the

input is not an

acceptable value

The function block can only control 1

to 16 axis. Any value greater or

smaller then this will cause an error.

This does not set the RDA Error ID.

<CHNGDYN> Working Register

This table outlines the data of six registers used in the function block. The user is, and

there is not a necessity and either is usually no what directly accessed any of these bits.

AW00000

Bit 0 IN execute Execute input (XB000000)

Bit 1 Working jerkOut Verifies that the SCURVE input (XW00001) is in range.

Bit 2 Working accelOut Verifies that the ACCEL input (XW00002) is in range.

Bit 3 Working decelOut Verifies that the DECEL input (XW00003) is in range.

Bit 4 Working velOut Verifies that the SPEED input (XW00004) is in range.

Bit 5 Working axisInErr Goes high for one scan if Axis input is out of range.

Bit 7 OUT Running Directly controls YB000000 (Running Output)

Bit 8 OUT done Directly controls YB000001 (Complete Output)

Bit 9 OUT Mistake Directly controls YB000002 (BlkFault Output)

Bit A Working osExecute Reserved

Bit B Working firstPass

One shot coil for initializing block on the rising edge of the

Execute bit.
