Mclennan Servo Supplies Ltd. Tel: +44 (0)8707 700 700 www.mclennan.co.uk These economic Unipolar drives conform to the international 3U Eurocard st andard They are ideally suited for use with the 4 phase permanent magnet or NEMA size 23 & 34 HS series hybrid stepper motors with current ratings from 0.08 to 3.1 amps per phase. The ability to operat e with rail voltages up to 30 V DC provide enhanced high speed performance with a choice of full step or half st ep phase control when improved low speed and mid range stability is achieved. The MSE162 utilises the L/4R drive principle. Series re sistors provide the necessary current forcing to obtain improved stepping rates. The selection of an appropriate resistor value enable a wide range of motors to be driven by MSE162 which offers the added benefit of low radiated electric noise. The addition of a chopped constant current output stage on the TM162C improves system efficiency and eliminates the need for the power consuming seri es resistors associated with the L/4R drive arrangement. Matching the motor to the Digitran drive is simplified by the provision of multi-position jumpers to enable motor phase current to be set between 0.3 & 2.0 amps per phase. Motor temperature rise and system power consumption may be minimi sed when the motor is at standstill by use of an external switch or control output, connected to the current control input. Furthermore the motor current can be externally adjusted by means of a remote potentiometer where alternat ive current settings are required. The units are controlled by clock pulses and direction signals that may either be 12V CMOS compatible for maximum noise immunity or of the open collector type. Alternatively the units may be fitted with the MSE210 voltage controlled oscillator which provides separate control for base and high-speed settings and an internal linear acceleration ramp. The MSE210 oscillator is ideally suited to applications where off-line manual control of the motor is required in the event of a control system failure or as an aid to commissioning. Additionally it may be used in conjunction with a PLC based control system to provide a return to datum function or simple position control using proximity switches for motor step rates up to 1000 half steps per second. Alternatively an on-board oscillator may be used.

Mclennan Servo Supplies Ltd. Tel: +44 (0)8707 700 700 www.mclennan.co.uk Starting (base) and running speed control The on-board oscillator can be arranged to start at a fixed frequency (thus a fixed motor speed) and then ramp up to a final value (the running motor speed). This facility is available to start the motor within its pull-in performance region and then accelerate the motor so that it can operate within the pull-out mode. On switch-off the motor decelerates automatically. Three parameters need to be determined for any application: A) The starting speed: this should be below the pull-in speed for the motor (with any additional load). B) The running (final) speed: this should be within the pull-out capability of the motor (with any additional load). C) The acceleration and deceleration rate between starting and running speeds: this is limited by the motor capability to accelerate through its own (plus any load) inertia.

Tel: +44 (0)8707 700 700 www.mclennan.co.uk A range of EM170 & PM170 series power supply modules have been developed for use with these Digitran drives with the choice single or multi-axis operation at a 24 V DC motor rail voltage. PM170 series power supplies are 19” x 3U high eurorack mounted units with sufficient space to fit either four digitran TM162C drives or a two axis control system comprising digitran drives & digistep controllers. When sequential control of motor position is acceptable; a single PM173 rack enables three TM162C drives to be mounted in the rack together with the PM381 based multiplexed intelligent controller.

Mclennan Servo Supplies Ltd. Tel: +44 (0)8707 700 700 www.mclennan.co.uk Current settings using TM162C / PM162C The motor phase current may be set to the most popular values using on board jumpers as shown below. Since the motor winding inductance may affe ct the actual current app lied by the drive, the actual phase current applied to the motor should be checked during commissioning when the motor is in a stationary condition. If necessary, adjus tment of the set value may be obtained by using a 100 KΩ potentiometer or a resistor connected betwe en pin 27 and 0V. This will allow an adjustment range of between 25% and 100% of the current value set on the links.

Mclennan Servo Supplies Ltd. Tel: +44 (0)8707 700 700 www.mclennan.co.uk Use with MSE210 Oscillator Module The MSE210 is an oscillator module for use with MSE162, PM162, TM162C and PM162C units. It has been designed to be fitted as a daughter board to the PCBs on plastic stilts and is connected via an IDC lead using the on-board connector SK1. A ll the control connections are then made via the host unit’s 32-way connector, see Fig 10. Two speeds may be set by external potentiomete rs; the base (or pull-in) speed and the high speed. These pots are fitted either externally or as preset trimmers on the appropriate motherboard. The oscillator may be switched on or off by the Stop/Run input and the speed is selected by the Base/High input. When the speed is changed (but not switched on or off), the rate of change of speed is set by the RAMP pot on the MSE210 board. There is also a Jog input for single stepping the motor. Do not use this whilst in Run mode.

Mclennan Servo Supplies Ltd. Tel: +44 (0)8707 700 700 www.mclennan.co.uk Motor connections using twisted wires. To produce the minimum amount of radiated noise, the motor leads should be of a twisted construction as shown below. The cable should be screened, with the screen connected to earth at the drive end and to the motor body at the motor end. In some hazardous environments, it is not permissible to earth both ends, because of the risk of high 50Hz circulating currents if the earth loop is cut by strong magnetic fields (in close proximity to very powerful electrical machinery). In this case the earth connection may be made with a 1.0µF capacitor rated at 250VAC. The motor body must be earthed.
