10.1.3.2Monitoring: telegram failure

Description

After a telegram failure and a monitoring time has elapsed (p2047), bit r2043.0 is set to "1" and alarm A01920 is output. Binector output r2043.0 can be used for an emergency stop, for example.

After a delay time has elapsed (p2044), fault F01910 is output. Fault F01910 triggers fault response OFF2 (pulse inhibit) for the supply and fault response OFF3 (emergency stop) for SERVO/VECTOR. If no OFF response is to be triggered, the fault response can be reparameterized accordingly.

Fault F01910 can be acknowledged immediately. The drive can then be operated even without PROFIdrive.

Figure 10-8 Monitoring: telegram failure

Example: emergency stop with telegram failure

Assumption:

A drive unit with an Active Line Module and a Single Motor Module.

VECTOR mode is activated.

After the ramp-down time has elapsed (p1135), the drive is at a standstill.

Settings:

CU p2047 = 20 ms

A_INF p2044 = 2 ms

VECTOR p2044 = 0 ms

Sequence:

After a telegram failure and the monitoring time has elapsed (p2047), binector output r2043.0 of drive object CU switches to "1". At the same time, alarm A01920 is output for the A_INF
