Second and third setpoint SK 500E (SW2/3)
In addition to setpoint 1, a second setpoint can be transferred in word PZD3 and a third setpoint in PZD4.
PZD1 PZD2 PZD3 PZD4
STW SW1 SW2 SW3
The second and third setpoints are always 16 Bit. The function of the second and third setpoints can be set
in
the inverter with parameter P547 „Setpoint 2 function‟ and P548 „Setpoint 3 function‟ respectively.
Both setpoints are transferred as whole numbers in the range -32768 to 32767. The value 16384 (4000
HEX) corresponds to 100%. The value C000 HEX is equal to
–100%, so that setpoints in the range
–200% to +200% can be transferred. A setpoint of 100% corresponds to the respective nominal value:
Setting 100% is equal to
