Supply
Active infeed
Operating modes of Active Infeed closed-loop control for Active Line Modules (chassis)
Active Line Modules (chassis) only function in active mode.
The DC link voltage setpoint (p3510) is preset in line with the
supply voltage (p0210) according to the following formula: p3510 = 1.5 * p0210.
Commissioning
During commissioning, the device supply voltage (p0210) and the rated line fre-
quency (p0211) must be parameterized. In addition, an optional line filter (p0220)
must be selected.
Note
In a supply system without regenerative feedback capability (e.g. generators),
regenerative operation must be inhibited via the binector input p3533.
The DC link voltage (p3510) can be set within the following limits:
S Booksize
-- Upper limit: Maximum DC link voltage (p0280)
-- Lower limit: Supply voltage (p0210) multiplied by 1.42
S Chassis
-- Upper limit: Supply voltage (p0210) multiplied by 2
-- Lower limit: Supply voltage (p0210) multiplied by 1.42
Note
If automatic commissioning was carried out with STARTER, the line filter (if used)
must be included in the configuration.
