Input the following ladder block to allow the inverter to enter "Ready For Switching On" sta-
tus, after connection is established, and initialization command is given (M0.0).
This initialization will result in setting bit 0 in ZSW1 (Ready To Switch On). It is now possible to
switch on the inverter, and start operation. To do this, enable bits 0 (ON/Off), 3 (enable oper-
ation), and 10 (Control By PLC); while leaving bits 1 and 2 enabled.
At this moment it is also possible to set the desired rotation frequency. Assuming the motor
is rated for 50 Hz (inverter parameter 3) and a frequency of 10 Hz is requested, set 20% of the
rated motor speed to achieve this frequency. The value in Profidrive to allow full power is
16384, so setting 20% of this value (3276,8 round to 3277) will give the expected result. This
value shall be set in NSOLL_A.
Add the following ladder block to enable rotation command after initialization, and giving ro-
tation command (M0.1).
