16.5.7.4 Speed and direction control of the movement
The following parameters are important for speed and direction control of the movement:
Characteristic value
Speed control
Direction control
Resolution of the speed setpoint
Relationship: Speed / Frequency
Name:
Mov01Speed
Mov02Speed
These registers are used to set the speed of the movement.
Data type
INT
16.5.7.5 Position feedback for movement
The position feedback is represented by a fixed point value [16.16]:
• HighWord = whole number increments
• LowWord = positions after the decimal of the increments
Name:
Mov01Position
Mov02Position
These registers show the current position of the movement.
Data type
DINT
Data sheet V1.21
Description
The predefined speed is specified as a percentage of the configured maximum speed.
0 to ±32767 correspond to 0 to ±100% of the configured maximum speed
The direction of movement is defined by the sign of the speed setpoint:
0 to +32767 correspond to 0 to the maximum speed in the positive direction of movement
0 to -32767 correspond to 0 to the maximum speed in the negative direction of movement
The resolution of the speed setpoint is:
Maximum speed / 32767
The relationship between speed and output frequency is:
(Speed setpoint / Maximum speed) * 32767
