Stepper Motor Drivers

TOPS provide three basic configurations for stepping drive electronics, including integrated motion controllers.

Each configuration is available as a complete boxed motion system or as a component level open-frame set of devices available for your own machine installation or electrical cabinet.
  1. Boxed motion systems include drive – controller – power supply – motors – gears – software – cables and connectors (plug & play).

  2. Open-frame component level assemblies contain drive electronics boards integrated drive and controllers software, with matching motors - gears - power supplies - cables and connectors all available separately.

Three basic drives exist:

  • SiNet™ programmer "Si"
  • X configuration "X"
  • Oscillator on board "O"

To help you choose the adequate stepping drive, please view our selection tables:

We also supply a family of stepper motors with integrated electronics, which offer a reduced footprint, easy connection and a lower cost: the STM series.

Full and Half-Step Drivers

T/P2035 • DC Full/Half Step Drive
0.125 A • 12-35 VDC • Pulse & Direction

2035 Drive
T/P2035
Details…

The T/P2035 step motor driver is a full or half drive, step phase sequencer with three state switching amplifiers and opto-isolated circuits. The drive also includes an automatic feature to lower motor current by 50% anytime the motor is left at rest for more than one second. This feature can be disabled.

The T/P2035 amplifier regulates motor current by chopping at a constant, inaudible frequency. Phase current is selected from 16 levels by a DIP switch. Full or half resolution is also switch selectable.


T/P2035O • DC Full/Half Step Drive w/ Oscillator
0.125 A • 12-35 VDC • Oscillator or Pulse & Direction

2035O Drive
T/P2035O
Details…

The T/P2035O step motor driver is a full or half step drive, step phase sequencer with three state switching amplifiers and opto-isolated circuits. This drive has a built in ramping pulse generator (oscillator) with adjustable speed, acceleration and deceleration. Oscillator speed range is 0–5,000 Hz. Speed can be set from on-board trimpot or external pot.

A jumper allows you to select the internal oscillator. In Oscillator mode, the pulse input becomes a run/stop signal: when this signal is set high, the motor accelerates to a preset speed and slews. Lowering the input signal causes the drive to decelerate to rest.

The amplifier regulates motor current by chopping at a constant, inaudible frequency. Phase current is selected from 16 levels by a DIP switch.


T/P2035XD • DC Dual-Axis Full/Half/Microstep Drive
2.0 A • 35 VDC • Oscillator 2 Axis Full • Half and Microstep Programmable Digital Oscillator, or Pulse & Direction

2035XD Drive
T/P2035XD
Details…

The T/P2035XD step motor driver is a two axis, software configured step/direction or oscillator drive. Drives can be quickly and precisely configured using our eXposition™ software and a Windows PC.

When configured for Pulse/Direction mode, the two drives can be commanded by the step and direction signals available from many PLCs and step motor indexers.

In oscillator mode, the two drives generate their own acceleration and deceleration profiles and are commanded by digital run/stop signals. These signals can be supplied by PLCs, mechanical switches, single board computers or other motion control devices. Speeds may be fixed or can be set "on the fly" by 0 to 5 volt analog signals.
