Positioning mode
The positioning mode is specified by determination of the control mode with the bits CDIR.COM1/2.
The position setpoint value is dependent, absolutely or relatively, on the bit CDIR.ABS.
The setpoint values are specified as follows:
Bytes
Content
Value
Setpoint values
Control byte 4
Setpoint value 1
Speed [% of the basic value]
è
PNU 540
Control bytes 5 … 8 Setpoint value 2
Position [SINC], 32-bit number
è
Actual values
Status byte 4
Actual value 1
Speed [% of the basic value]
è
PNU 540
Status bytes 5 … 8
Actual value 2
Position [SINC], 32-bit number
è
Tab. 6.13
Setpoint and actual values – direct application positioning mode
After the setpoint specification, travel to the position in accordance with the setpoint values begins
with the start signal (start bit) and the active position control mode is displayed via the SDIR.COM1/2
bits.
The signal “Motion Complete” (MC) reports “Position reached” in this control mode.
Speed mode (speed adjustment)
The speed mode is specified by determination of the control mode with the bits CDIR.COM1/2. The
speed setpoint value is always absolute; CDIR.ABS is ignored.
The setpoint values are specified as follows:
Bytes
Content
Value
Setpoint values
Control byte 4
Setpoint value 1
Speed ramp [% of the basic value]
è
PNU 560
Control bytes 5 … 8 Setpoint value 2
Speed [SINC/s]
è
Actual values
Status byte 4
Actual value 1
No function, = 0
Status bytes 5 … 8
Actual value 2
Speed as absolute value [SINC/s]
Tab. 6.14
Setpoint and actual values – direct application speed adjustment
After the setpoint specification, with the start signal (start bit), the speed is built up in the direction
indicated by the prefix of the setpoint value 2 and the active speed control mode is displayed via the
SDIR.COM1/2 bits.
The signal SPOS.MC (Motion Complete) in this control mode reports “target speed reached”.
