Relative target position: Intended for use with AB rotary encoders or pulse generators.
Each count received (if applicable: Each mechanical detent) triggers relative motion of the
mechanical axis by a set distance.
Information
Motion commands are not permitted when HID control is enabled for the axis.
HID control is not possible in open-loop operation (servo mode Off).

HID Control Configuration
Control of the axis/axes connected to the E-871.1A1N by the HID's axes is configured via the
command. The current HID control configuration can be queried with the
command. The direction of motion of HID-controlled axes can be inverted via the Invert
Direction Of Motion For Joystick-Controlled Axis? parameter (0x61).
Assigning a lookup table to an HID axis is done with the
command. The current lookup
table assignments to HID axes can be queried with the
lookup table are factors that are applied to the motion parameter to be controlled during HID
control. The E-871.1A1N's firmware gives a choice of two predefined lookup table types
(linear and parabolic) and allows four customer-specific lookup tables to be filled with
individual values. Lookup tables can be filled with values with the
queries the values of the points in the lookup tables.
Use the
command to activate/deactivate HID control of the axes connected to the
E-871.1A1N. The
command queries the activation state of HID control. When HID
control is deactivated, the target position is set to the current position of the controlled axis.
The
command queries the properties of the HID's operating elements. The current
status of the HID buttons can be queried with
and the current displacement of HID axes
.
Setting the distance (stepwise) for relative motion triggered by an HID is done by the
command. The currently set step size can be queried with
.

Programming HID Control
HID output units (e.g., buttons and LEDs) can be used for example, in controller macros to
program HID control.

E-871.1A1N's connector for a manually operated device such as a joystick or gamepad
Tools and Accessories
■
If the relative target position of the E-871.1A1N's axis is to be controlled with the HID:
■
Rotary encoder or pulse generator for manual operation, type of output signals: AB,
maximum 500 Hz, TTL
■
If the absolute target position of the E-871.1A1N's axis is to be controlled with the HID:
■
Analog joystick for operating with 0 to 3.3 V, e.g., C-819.20 or C-819.30 (available as
optional accessory)
■
If a C-819.20 joystick is to be connected to two controllers: C-819.20Y Y cable (available
as optional accessory)
