Settings in drive 2 (subscriber)
Drive 2 is preset in such a way that it receives its setpoint from the higher-level controller. In
order that drive 2 accepts the actual value sent from drive 1 as setpoint, you must set the
following:
● In drive 2, set the PROFIdrive telegram selection to "Free telegram configuration" (p0922
= 999).
● In drive 2, set the source of the main setpoint to p1070 = 2050.3.
The inverter indicates the inverter addresses that are configured for direct data exchange in
parameter r2077.
