OEM-SPECIFIED PARAMETERS
(SET AT FACTORY)
In addition to the programmable parameters described in Section 3, there are
various parameters that can be set at the factory per the OEM’s specification.
These parameters are not programmable with the 1307 programmer. If a change
is desired, the controller must be returned to the factory for reconfiguration.
SPEED INTERLOCKS
The speed interlocks prevent the speed parameters from being inadvertently
programmed to give abnormal operating characteristics.
The following relationships are ensured by the speed interlocks.
The minimum speeds can never be set higher than the corresponding
maximum speeds:
• M1 Min Speed cannot be set higher than M1 Max Speed
• M2 Min Speed cannot be set higher than M2 Max Speed
Mode 2 is by definition the faster of the two modes:
• M1 Max Speed cannot be set higher than M2 Max Speed
Reverse speed, which applies in both modes, must be within the Mode 1
speed range, and can never be lower than 25%:
• Reverse Speed must be set between M1 Min Speed
and M1 Max Speed
• Reverse Speed can never be set at less than 25%.
The speed interlocks can be disabled at the factory, if so desired. However,
this is not recommended unless a specific application requires that the existing
speed interlock relationships be violated.

SPEED LIMIT POT FAULT
The speed limit pot fault function provides a check to determine whether the
speed limit pot wiper is correctly connected. If a wiper input is not detected, the
controller limits its maximum speed to the specified minimum speed (i.e., the
