VAR
co_clear_revolution_counter
_cmd
U8
1
RW
n
0
0-1
Writing 0x0 1 clears sensors software based revolution counter. Always 0
after boot up.
2001
VAR
co_counted_revolutions
I16
2
RO
y
0
Number of counted revolutions. After reset value is 0. Writing to
co_revolution_counter_config object sets value to 0.
2002
VAR
co_speed_difference_time
U16
2
RO
n
100
4-300
Indicates difference time in sensor speed calculation. Is depended on
co_speed_buffer and co_CAN_time.
2003
VAR
co_speed_buffer
U16
2
RW
n
10
2-30
Sensor speed calculation buffer length. The longer buffer the slower
rotation is allowed!! More information in chapter 6.2
2004
VAR
co_serial_cmd
U8
1
RW
n
0
This object controls serial printing.
0 = printing is off
1 = prints position, speed, and counted revolutions, interval is object
value times 10 ms
2010
VAR
co_32bit_speed_value
I32
4
RO
y
0
Sensor speed as units per second, which is calculated from position
values. 32 bits
2100
VAR
co_calib_cmd
U8
1
RW
n
0
Start calibration by writing “1” into this while co_calib_cmd_status is 1.
2101
VAR
co_calib_cmd_status
U8
1
RWP
n
0
0 = non calibrated sensor
1 = allow calibration command
2 = calibration in progress
3 = sensor is calibrated
4 = sensor calibration failed, previous values restored
2102
