How to configure the safety encoder interface

To configure the safety encoder interface, set the drive and FSO parameters listed
below to appropriate values using the Drive composer pro PC tool. See parameter
groups Safety, S_ENCGEN,
(92) on pages 322
Example: The pulse encoder interface module type is FSE-31 and it is installed in
Slot 2 on the drive control board. One HTL encoder is used.
Set these drive parameters in the Parameters view of the Drive composer pro PC
tool:
• The motor speed feedback during motor control is from Encoder 1:
90.41 Motor feedback selection = Encoder 1
• The drive generates a warning if an encoder failure occurs:
90.45 Motor feedback fault = Warning.
• Encoder cable channels A, B and Z are monitored for wiring faults:
92.21 Encoder cable fault mode = A, B, Z.
Set these FSO parameters in the Safety settings view of the Drive composer pro PC
tool:
• Communication with the FSE module activated:
200.231 FSE 3X act and par version
• One safety encoder is connected to the FSE module:
200.232 Number of encoders
• Safety encoder activated:
S_ENCGEN. 01 Safe pulse encoder version
• The FSO module activates the drive STO function if there is a problem with the
FSE module: S_ENCGEN. 11 FSE diagnostic failure reaction
• Cross comparison tolerance: 5 rpm (sets how much the axle speed of the motor
can change within 1 ms)
S_ENCGEN. 14 Enc speed cross comp tolerance
• Rotation direction not changed:
S_ENCGEN. 41 Gear numerator encoder 1
• 91.11 Module 1 type
• 91.12 Module 1 location
• 92.01 Encoder 1 type
• 92.02 Encoder 1 source
• Number of HTL pulses per rotation:
Note: Make sure that the value is according to the encoder nameplate.
