Sauter Turret is not working correctly

[Denford Admin]

We are having problems with our Sauter Turret which is fitted to a Mirac / Meteor lathe

[Denford Admin]

The fault will lie with a toolpost sensor / relay / or toolpost drive

To help identify the problem, here is the sequence of events for a tool change to tool number 5:

' Change Sauter tool post change sequence - Typ 0.5.480.408


Check if already at requested position - if TRUE then EXIT

Work out shortest path to target - FWD or REVERSE - eg, FWD

Turn Tool post shotpin OFF [TPSR][TB3-9][Output 7]=0

Go FWD
[TPFR][TB3-7][Output 5]=1
[TPRR][TB3-8][Output 6]=0

Wait for NOT tool post strobe [TB8-5][Input 18] =0
Wait for tool post strobe [TB8-5][Input 18] =1

Wait for tool position matching (For example, Tool 5 = 0101)
Tool Position Bit 0 = [TB9-6][Input 3] = 1
Tool Position Bit 1 = [TB9-7][Input 4] = 0
Tool Position Bit 2 = [TB9-8][Input 5] = 1
Tool Position Bit 3 = [TB9-9][Input 6] = 0

Wait for tool post strobe [TB8-5][Input 18] =1
Wait for NOT tool post strobe [TB8-5][Input 18] =0

Turn Tool post shotpin ON [TPSR][TB3-9][Output 7]=1

Wait for NOT shotpin sensor [TB9-10][Input 7]=0

Go REV
[TPFR][TB3-7][Output 5]=0
[TPRR][TB3-8][Output 6]=1

Wait for tool post strobe [TB8-5][Input 18] =1

Turn Tool post shotpin OFF [TPSR][TB3-9][Output 7]=0

Stop Motor
[TPFR][TB3-7][Output 5]=0
[TPRR][TB3-8][Output 6]=0

Wait for shotpin sensor [TB9-10][Input 7]=1

Check position and time out if position is not correct or shotpin sensor=0

You can also try the magic M27 command, which will reset the turret into a random position, if it has failed to clamp up previously - it basically send the turret one way, reverse it to clamp, sends it the otherway and reverses again to finally clamp up (it is to reset the mechanisms inside the turret which force you to clamp in the opposite direction to the initial direction of rotation)
