a: very low encoder resolution
Enables a choice between one of the 4 ramps available, according to the table below.
Same as Ramp bit 0.
Mains Failure
Activates par. 14-10 . Mains failure inverse is active in the Logic .0. situation.
Sends a latched stop signal when the precise stop function is activated in par. 1-83
Function
. The Latched Precise stop inverse function is available for terminals 18 or 19.
INCREASE signal to the Digital Potentiometer function described in par. group 3-9*
DECREASE signal to the Digital Potentiometer function described in par. group 3-9*
Clears the Digital Potentiometer reference described in par. group 3-9*
(Terminal 29 or 33 only) Input for increment counting in the SLC counter.
(Terminal 29 or 33 only) Input for decrement counting in the SLC counter.
Input for reset of counter A.
(Terminal 29 or 33 only) Input for increment counting in the SLC counter.
(Terminal 29 or 33 only) Input for decrement counting in the SLC counter.
Input for reset of counter B.
Brake feedback for hoisting applications: Set par 1-01 to [3]
Hoist mech brake Ref.
to [6]
Inverted brake feedback for hoisting applications
When enabled, it inverts the resulting error from the process PID controller. Available only if "Con-
figuration Mode" is set to "Surface Winder", "Extended PID Speed OL" or "Extended PID Speed CL".
When enabled, resets the I-part of the Process PID controller. Equivalent to par. 7-40. Available
only if "Configuration Mode" is set to "Surface Winder", "Extended PID Speed OL" or "Extended PID
Speed CL".
When enabled, enables the extended process PID controller. Equivalent to par. 7-50. Available only
if "Configuration Mode" is set "Extended PID Speed OL" or "Extended PID Speed CL".
All Digital Inputs can be set to PTC Card 1 [80]. However, only one Digital Input must be set to this
choice.
