Support and Troubleshooting
7-11
7.4.18 Command pressure cannot be less than pressure set
B
When using Pressure Set Mode, the Command Pressure—which is issued as the Command
Value in a Set Pressure command—must always be greater than or equal to Pressure Set B.
7.4.19 Dead band eliminator out of range
This parameter error indicates that the DEAD BAND ELIMINATOR parameter was set to a value
greater than ±2000. This maximum prevents a dead band of greater than 2 volts. If a valve still
does not work to satisfaction with this large of a dead band, then the valve is most like not
appropriate for the job. Refer to Hydraulic System Problems for details.
7.4.20 Drive transfer percentage out of range
This parameter error indicates that the DRIVE TRANSFER PERCENT was set to a value outside
the maximum range of ±500. The value will have been truncated to fit in this range. Change this
parameter to a value inside the range and issue a Set Parameters command.
7.4.21 "Event Step Edit" indices are invalid
The Programmable Controller sets the beginning and ending step numbers to edit with the E0
and E1 Event Step Edit commands. When the E3 Event Step Edit command is issued—which
actually performs the step table modifications—the beginning and ending step numbers are
checked. Both must hold valid step numbers (between 0 and 255, inclusive), and the ending step
number must be greater than or equal to the starting step number.
If the beginning and ending step numbers are out of range or reversed, this parameter error is
generated.
7.4.22 Extend limit must be greater than retract limit
This parameter error indicates that the EXTEND LIMIT was set to a position in which the
TRANSDUCER COUNTS would be less than or equal to those at the RETRACT LIMIT position.
Therefore, if the SCALE is positive, this error indicates that the EXTEND LIMIT is less than the
RETRACT LIMIT. Otherwise, this error indicates that the EXTEND LIMIT is greater than the
RETRACT LIMIT.
7.4.23 Feed forward terms must have the same sign
On pressure axes it is possible to use both positive and negative values for gains and feed
forwards. However, all should have the same sign. If the EXTEND FEED FORWARD and
