Drive-specific (crane) control
The drive-specific (crane) control is integrated in the SIMOTRAS HD converter. It is made up of the
freely assignable function blocks (technology software S00). The freely assignable function blocks
are shown in Section 8, sheets B100 to B216. In the factory settings for the relevant parameters,
these function blocks are connected to the drive-specific (crane) control as shown in Section 8,
sheets K1 to K18.
The drive-specific (crane) control has been designed to simplify the switchover between the master
switch with setpoint potentiometer and the 4-stage master switch:
U251 = 0:
U251 = 1
The control functions can be entered via the terminals or PROFIBUS (SINEC L2 DP). If a T300
technology board and/or a CBP board is inserted, the control functions are automatically entered
from the T300 or from PROFIBUS. The terminals 36, 37, 39 and 72 to 79 have no function. The bit
assignments for the control inputs on the PROFIBUS are shown on sheets K4 and K5 in Section 8.
The following diagram shows the arrangement of the pre-limit switches and the limit switches,
together with the direction of the travel command as required for operating the crane control.
