Type Axis parameter
Syntax SPEED_SIGN
Description The SPEED_SIGN parameter configures the voltage range of the ana-
logue speed reference output of the Encoder Interface when the axis
type
ATYPE is set to 44.
If SPEED_SIGN = OFF , the voltage range of the analogue speed refer-
ence output is [-10V, 10V]. The positive reference voltage corresponds
to forward movements, in which case
DPOS and MPOS increment. The
negative reference voltage corresponds to reverse movements, in
which case
DPOS and MPOS decrement. OFF is the default setting at
power-on.
If
SPEED_SIGN = ON , the voltage range of the analogue speed refer-
ence output is [0V, 10V]. The OUT1 signal of the Encoder Interface for
the corresponding axis is used as a direction signal. During forward
movements, the controller sets OUT1 to OFF. During reverse move-
ments, the controller sets OUT1 to ON. This setting is to be used for
Servo Drivers that require both speed and direction signals as a speed
reference.
