Current Position
This parameter indicates the current position of the transducer in degrees and cents of degree. The actual resolution depends on the
type of transducer mounted in the motor and the resolution of it. This parameter can be useful to read the position and then set it to
one of the 4 available quotas and then command positioning.
NOTE:
In case of use of a multipolar resolver (from 4 poles upward), the indicated position is NOT the actual position of the
motor shaft, but that of the sinusoid currently generated by the resolver. For example, if a 6-pole resolver is used, it generates 3
complete sinusoids for each revolution of the transducer; so for every revolution of the motor shaft you will see on this parameter
a signal that goes 3 times from 0 to 360°.

Degrees
Set the position to reach and maintain the motor shaft when “quota 0 " is selected and motor positioning enabled.
NOTE:
This value can be changed via an analog input connected to Connector X11 (see page 17) after selecting this parameter as
the destination (see parameter “An.Inp. X dest“ on page 41).

Jog Function
Set of parameters to adjust the function of JOG (see paragraph "JOG function“ on page 71).
Jog ref. Mode
With this parameter you can select the mode of the Jog function. The possible selections are as follows:
•
FIXED REFER: When you enable the Jog function with the selectable input (standard on DI2), the motor rotates at a fixed
speed that is set to the parameter “JOG ref. Speed". When you disable the Jog function with the digital input, the motor
“locks " the normal speed reference.
•
SQUARE WAVE: When you enable the Jog function with the selectable input (standard on DI2), the function generates a
“Square Wave " with a period that can be set in the parameter “JOG wave Time" and with an amplitude of ± the speed set in
the parameter “JOG ref. Speed "; so the motor rotates at the speed set for a certain time and then reverses the direction and
turns backwards and continues in this way until the JOG control is removed.
•
TRIAN. WAVE: When you enable the Jog function with the selectable input (standard on DI2), the function generates a
“Triangular Wave" with a period that can be set in the “JOG wave Time " parameter and with an amplitude of ± the speed set
in the parameter “JOG ref. Speed"; therefore the motor gradually accelerates to the speed set with the set time and then slows
down gradually until it reverses the direction and reaches the set speed (inverted sign). Then it slows down again and
continues like this until the JOG command is removed.
