ESP-SPAC-CAM1 – Software Package Cam V1.4 (
LenzeCamControl1V0104.lib library)
Eliminated function restriction
When using the
LenzeCamControl1V0104.lib library cam signals were sporadically not switched on or off or in contrast to their definition they were not active at all or remained activated over several clock pulses. The problem occurred if
- the velocity exceeds a certain limit value which depends on the distance between the switch-off point and the end of the clock pulse or on the distance between the beginning of the clock pulse and the switch-on point of the cam signal.
- a path-based cam is reset at the end of a clock pulse when running with positive velocity or
- a path-based cam is reset at the beginning of a clock pulse when running with negative velocity
Moreover, the following behaviour occurred when using the
LenzeCamControl1V0104.lib library. Travel cams depending on the direction of rotation ('positive travel cam', 'negative travel cam') were not switched on again if the direction of rotation was inverted several times in one clock pulse.
The behaviour described before does not occur any longer when using the
LenzeCamControl1V0104SP2.lib library included in the Service Pack.
Note:
Due to the modifications made in the function block, the CPU time of the
L_CamContactor function block prolongs, depending on the cam type selected, by up to 8 μs compared to version V1.4. Since this function block may typically be used in different instances for several times, the cycle is prolonged accordingly.
As part of the revision of the
L_CamContactor function block the behaviour of this function block included in the
LenzeCamControl1V0104SP2.lib library differs slightly from the previous versions. The following differences exist:
