15/* */
16/* * V0.70: */
17/* - Implemented switch off of motor in case of Input 6 has a */
18/* falling edge */
19/* - moved the arbitrary factor 4 for the tracking speed from */
20/* cosy to here */
21/* */
22/* * V0.69: */
23/* - Implemented Pre-Operational/Operational state */
24/* means: + cannot start RPM mode */
25/* + SDO 0x6004 (POSA/POSR) ignored */
26/* + new SDO 0x1000 */
27/* */
28/* * V0.68: */
29/* - Made NoWait=On the default */
30/* - Implemented error 89 (CAN I/O) */
31/* - changed "REOPEN 0 0" to "REOPEN 1 0" */
32/* */
33/* * V0.67: */
34/* - trying to implement the control cabinet stuff */
35/* */
36/* * V0.66: */
37/* - implemented canopen node guarding (0x4000) */
38/* - implemented some kind of host guarding (in conjuction with */
39/* the implemented nodeguarding) */
40/* - removed old guarding using SDO 0x4000 */
41/* - implemented SDO 0x100c (guardtime) */
42/* - implemented SDO 0x100d (lifetimefactor) */
43/* */
44/* * V0.65: */

54/* */
55/* * V0.62: */
56/* - changed handling of 0x2000/1/2 added /3 */
57/* */
58/* * V0.61: */
59/* - corrected problems with the error handling */
60/* */
61/* * V0.60: */
