Some trivial questions about the Masso HTG5A1S controller

Greetings.
I have some trivial questions about the Masso HTG5A1S controller:
1.- The HTG5A1S controller works with negative or positive logic?
2.- The HTG5A1S controller was designed to control position, speed or torque?
3.- The command of the pulse train that leaves the HTG5A1S controller of what type it is?
3.1- Open collector system?
3.2- Differential receiver system?
3.3- Other? Which one?

Thanks

1.- The HTG5A1S controller works with negative or positive logic? - is this for inputs, sorry not clear about your question.
2.- The HTG5A1S controller was designed to control position, speed or torque? - position control
3.- The command of the pulse train that leaves the HTG5A1S controller of what type it is? - Pulse and Direction
3.1- Open collector system? - Inputs via Optocouplers
3.2- Differential receiver system? - not clear about the question
3.3- Other? Which one? - not clear about the question

In technical advice about what kind of servo amplifiers MASSO HTG5A1S controlled, Masso said he controlled the amplifiers with control signal as in the attached figure, that type of signal in the servo amplifier MR-J3-A is from NEGATIVE LOGIC.
That's why it's my question:
What type of control logic is normally sent by the Masso HTG5A1S controller on the output pins of the X-axis Y and Z?
Thank you

The positive and negative logic means the direction of the motor turning.

You need to set your drive to work on Pulsetrain + sign

The connection of the pins of the pulse train forward or reverse in an amplifier MR-J3-A depends on the system of the pulse input.

I quote from the manual MR-J3-A (Page 91, Section 3 Signals and Wiring):

"Used to enter a command pulse train.
- In the open collector system (max input frequency 200kpps)
Forward rotation press train across PP-DOCOM
Reverse rotation press train across NP-DOCOM
- In the differential receiver system (max input frequency 1Mpps)
Forward rotation press train across PG-PP
Reverse rotation press train across NG-NP "

What system should I use with the Masso HTG5A1S controller?
Thank you
