RE 30126-01-B/08.07 | Manual

Current (b22/b24)

Ramp+ (b6/b8)

Ramp- (b18/b20)

By using the mouse to click on the „Type" field a pull-down menu will open from which
Type
the following options can be selected:
n
+/-10 V
The input signal has a range of (–10 V) to (+10 V).
n
0~10 V
The input signal range is from (0 V) to (+10 V).
Further adjustment to the input signals is explained in greater detail in the section
"Configure Analog I/O - Inputs".
Type The range for the external setpoint using the Current input (b22/b24) is configured for
4-20 mA and can not be changed.
Further adjustment to the input signals is explained in greater detail in the section
"Configure Analog I/O - Inputs".
This value determines the external ramp used to ramp the command signal when the
setpoint is a rising edge in positive (Solenoid A) or negative (Solenoid B) direction.
Clicking on the „TYPE" entry field opens a pulldown menu containing the following:
Type
n
0~10 V
An input signal of (0 V) to (+10 V) is expected.
n
4~20 mA
The current value of the input signal ranges from (4 mA) to (20 mA).
For additional configuration of the Ramp+ please refer to Section "Configure Profile"
