è
Enable operation
Requirements:
– The I/O interface is selected as control interface
(
è
4.4.1 Create new drive configuration/change drive configuration).
– No error is present.
– The signals STO1=1, STO2=1 and ESTOP=1 must be present at the inputs of the interface for
switch-off functions [X4] (
è
3.2.5 Switch-off functions interface [X4]).
1. As soon as the controller is ready, RDYEN=1 and MC=1 are present.
2. Enable the drive and operation by applying the signal ENABLE=1.
– After the drive is enabled, the signal ENABLED=1 is applied.
The operation is enabled.
Carrying out homing
Homing is executed by selecting and starting record number 0.
Requirements:
– The position of the axis zero point AZ was correctly parameterised via the FCT.
– The drive is enabled with ENABLED=1, and no error is present, FAULT=0.
– START=0 must be applied.
– ACK=0 and MC=1 must be applied.
1. Select homing (record number 0) by applying the signal DIN1 … DIN5=0 to all five binary-coded
inputs (pin 2 … pin 6).
2. Apply the signal START=1 to start homing.
– The selected record number (record number 0 = homing) is taken over and started through a
rising edge at START.
– The signal ACK = 1 is applied as soon as homing has been started.
– As soon as the reference position is reached, the signal MC=1 is applied.
