Trio Motion Technology
Notes:
MotionPerfect2 contains support for commissioning SERCOS rings. This tool simpli-
fies the creation of a TrioBASIC startup program which consists of SERCOS state-
ments to initialise the ring following power-on, and configure the ring in the
deterministic cyclic phase.
SERVO_PERIOD
Type:
System Parameter
Description:
This parameter allows the controller servo period to be specified. On the MC202,
MC216 and Euro205 controllers this period is specified in seconds and on the MC206
controller it is specified in microseconds. It is recommended not to adjust the
default 1msec servo period on the MC202 and Euro205 controllers or where the
stepper daughter board is being used. Where the MC216 is being used for servo
axes the servo period may be adjusted down to around 0.0005 seconds.
Note:
The Motion Coordinator must be reset using the
EX
command before the new servo
period will be applied.
On the MC206 the servo period may be set to 1000,500 or 250 usec.
