s_set_Slave
Accelerate drive up to
speed of running
machine
<1> With a rising edge, position setpoint output is set
once to the set value.
<2> WEffect of the "Enable synchronism" command:
0 = Synchronism block is not calculated,
KK0310 = set value, all other outputs = 0
1 = Synchronism block is calculated,
at a 0/1 edge, the integrator is set to the set
value (normally to position actual-value)
<3> The examples are applicable if the motor encoder
[330] is used. If an external machine encoder is
used, the corresponding parameters and
connectors on sheet [335] have to be used.
<4> Application example see Chapter 9.4.40
<5> If the new function "Continue synchronism" is
activated via binector input U674.2 the internal
values/statuses are frozen. No internal reset of
values/statuses takes place. Thus when
synchronism is temporarily deactivated it behaves
as if it had never been shut down.
