Hi ulda
Thankyou for your reply.
Yes would very much like to see your configuration files.
I do have the logic documentation pages, but the machine was a not running when I obtained it so I have never run the spindle.
Think I can see a lot of what is occurring from the spindle speed table and the diagram of the three gear selection motors
rotating CCW each has three micro-switches representing nine bits in total, for inputs when the motors are driven into the correct gear position for the speed selected they trigger three outputs that switch off each of the 3 three selection motors in that sequence, please correct me if I am wrong.
I was originally going to use just an inverter only for spindle, but I like the look of the gearbox and the spindle power advantages it gives, the two speed motor may only be used in the high range (2800rpm) because it only covers 31,40,50rpm speeds at (1400rpm) and the motor control and switching on / off /direction, all done by the inverter in place of the old mass of reversing control contactors.
Regards
Gary

I am currently in the proces of retrofitting a maho 400c.
But i am still getting all the information...
Does your maho 700 has a indramat 3trm2 servo amp?

I'm currently doing a lathe that has the 3TRM2 drive. Just got the servos up and running properly this morning. Maybe I can answer some of your questions?

Yes, my mh700 has this 3trm2 (1 amp for 3 servos) and an additional one for the B/C Axis.
It has +/- 10V input for velocity - works fine with me.
How can we help?

Basically i don't know how to connect everything to ma cards, because i don't know what most connectors are.
Some things may be obvious but i would like to be sure before i mess something up completely.
if you can tell me how to connect everything that would be super, i am a complete newby to servo amps and servo's so any information is welcome.
Ther 3trm2 has the following connectors:

Hi everybody
I mailed this to peter, but here it is for everybody to use:
I mailed this to peter, but here it is for everybody to use:
I had to find my wiring plans, Sorry for the delay.
This are the pinouts for the Connectors L1 to L7:
L1, L2, L3 (controller signal input)
101 201 302 JF+: Enable pulse +
102 202 301 JF-: Enable pulse -
RF : Enable control
GND
OVM
E103 (Tacho): Tacho input against 0VM
GND
E101 E201 E301 : Velocity setvalue (against 0Vm)
E102 E202 E302 : Velocity setvalue (against 0Vm)
(E101/E102 are selected internally, same for E201/E202 and E301/E302)
0VM
L4 (controller ready relay)
Bb2: Relais contact: internal 24V current ok
Bb1:
L5 (syncronisation)
Sy1: Synchronisation for axis 1
Sy2: Synchronisation for axis 2
Sy3: Synchronisation for axis 3
(Sy1-Sy3 are bridged internally to L6 sy)
L6 (contoller voltage regulator)
R Phase for control voltage (380V)
S Phase for control voltage
24Vl+ controller switch power
0Vl base for switch power
+15V controller setvalue power
0Vm base for setvalue power
GND
-15V controller setvalue power
sy syncronization signal
L7 (motor voltage control)
A1: Motor 1 out (against N Impedance / GND of controller)
A2: Motor 2 out (against N Impedance / GND of controller)
A3: Motor 3 out (against N Impedance / GND of controller)
U1: Phase U for controller 1/Motor1 (from impedance)
V1: Phase V for controller 1/Motor1 (from impedance)
U2: Phase U for controller 2/Motor2 (from impedance)
V2: Phase V for controller 2/Motor2 (from impedance)
U3: Phase U for controller 3/Motor3 (from impedance)
V3: Phase V for controller 3/Motor3 (from impedance)
On the Picture you can see my wiring:
* JF+ = JF- = RF are switched to Ul+ by a relais for "enable axis" (one signal
for all 3 axis)
* JF+ and JF- can be used for limit switches input.
* OVM/E103(Tacho)/GND go to the tacho generator of the axis' motor
* 0VM/E302/GND go to my velocity output signal DA ± 10V (I wired together two
lines of the cable)
* alternaviely you can use +15V / -15V / 0Vm for driving these pins.
