Actual signals and parameters
Description
Unipolar analogue input AI1 as joystick. The minimum input signal runs the
motor at the maximum reference in the reverse direction, the maximum input at
the maximum reference in the forward direction.
Note: Parameter 10.03 REF DIRECTION must have the value REQUEST.
Start DI direction, if used (10.01
WARNING! Minimum reference for joystick must be higher than 0.5 V.
Set parameter 13.01
0.5 V and analogue signal loss detection parameter
FUNCTION to FAULT. The drive will stop in case the control signal is lost.

Par. 13.01 = 2 V, Par. 13.02 = 10 V
Note: If the signal is bipolar (±10 V DC), use the selection AI1 BIPOLAR. The
selection AI1/JOYST ignores the negative signal range.
See selection AI1/JOYST.
Digital input 3: Reference increase. Digital input DI4: Reference decrease.
Stop command or power switch off resets the reference to zero. Parameter
22.04 ACCEL TIME 2 defines the rate of the reference change.
Digital input 3: Reference increase. Digital input DI4: Reference decrease. The
program stores the active speed reference (not reset with a Stop command or
power switch-off). Parameter

See selection DI3U, 4D.
Fieldbus reference REF1
As with the selection COMM. REF, except the following differences:
- shorter communication cycle time when transferring the reference to the core
motor control program (6 ms -> 2 ms)
- the direction cannot be controlled through interfaces defined with parameters
10.01 or 10.02, nor with the control panel
Note: If any of the following selections is true, the selection is not effective.
Instead, the operation is according to COMM. REF.
- parameter 99.04 MOTOR CTRL MODE is SCALAR
