-1 Feed constant denominator.
60.08 POS2INT SCALE FW block: POS FEEDBACK (see above)
Scales position values to integer values. Integer values are used in the control program and fieldbus
communication. For positioning speed, acceleration and deceleration value scaling, see parameter
60.11 POS SPEED2INT.
Example: If parameter value is set to 100 and 60.05 POS UNIT is set to (2) METER, integer value of
3000 corresponds to position value of 30 m.
1/10/100/1000/10000/
100000/1000000
Scaling factor.
60.09 POS RESOLUTION FW block: POS FEEDBACK (see above)
Defines how many bits are used for the position count within one revolution.
Example: If parameter is set to a value of 24, 8 bits (32 - 24) are used for the whole revolution count
and 24 bits are used for the fractional revolution count.
Note: This parameter cannot be changed while the drive is running.
10…24 Number of bits used for position count.
60.10 POS SPEED UNIT FW block: POS FEEDBACK (see above)
Selects, together with parameter 60.05 POS UNIT (position unit), the unit for positioning speed,
acceleration and deceleration values.
(0) U/S Position unit/s (s = second). With acceleration/deceleration values:
position unit/s
2
.
(1) U/MIN Position unit/min (min = minute). With acceleration/deceleration
values: position unit/min
2
.
(2) U/H Position unit/h (h = hour). With acceleration/deceleration values:
position unit/h
2
.
60.11 POS SPEED2INT FW block: POS FEEDBACK (see above)
Scales all positioning speed, acceleration and deceleration values to an integer value. Integer values
are used in the control program and fieldbus communication.
Example: If parameter value is set to 10, an integer value of 10 corresponds to positioning speed
value 1 rev/s.
1/10/100/1000/10000/
100000/1000000
Scaling factor.
60.12 POS SPEED SCALE FW block: POS FEEDBACK (see above)
Defines an additional scaling for internal positioning speed, acceleration and deceleration values. Can
be used e.g. to improve calculation accuracy at low and high speeds.
Example: If parameter value is set to 0.1, internal speed value 1 rev/s is changed to value 10 rev/s.
