Bolt directly onto RTA drives. No external power supply needed. Ramped
or non ramped cards available. No computer configuration required. |

| The RTA stepping motor drives will cause a motor to rotate one step whenever a clock pulse is fed into the drive. These clock pulses are usually generated by microprocessor based controllers, computers and programmable logic controllers. However, in many small single axis applications such as labelling machines, packaging machines and variable speed systems the expense of these sophisticated controllers and accosiated computers is not justified. |
The RTA osscilator cards produce clock pulses required for typical industrial applications and are designed specifically for motion control. They fit directly onto the GMD, GMH, GAC, BCW drives, deriving the +12V power supply from the drive. All settings are made by dip switches and potentiometers.

OFM30 The OFM30 is a non ramped osscilator with fixed frequency. When the STEP ENABLE input is pulled low to 0V, a continuous pulse train is produced. When this input is is disconnected or left high, the pulse train is stoped. An LED is illuminated when the motor is running. The pulse train frequency is adjusted by dip switches and an on board trim potentiometer. Alternativly, speed can be controlled by an external potentiometer. Speed range is 40Hz to 5000 Hz. |

OFM40 The OFM40 is a non ramped osscilator similar to the OFM30. When the START input is pulled low momentarily to 0V, a continuous pulse train is produced. When the STOP input is pulled low momentarily to 0V the output pulse train is immediatly stopped. The pulse train frequency is adjusted by dip switches and an on board trim potentiometer. Alternativly, speed can be controlled by an external potentiometer.Speed range is 40Hz to 5000 Hz. |

OFM40E This has the same characteristocs as the OFM40 except that the speed is determined by an encoder input rather than a potentiometer. For each encoder pulse fed into the OFM40E a pulse will be output. The START and STOP inputs switch the output pulses off and on. This is useful in velocity following and cutting 'on the fly' applications. |

VOM This osscilator card is designed for manual control applicatrions and has two control inputs. The ENABLE input will run the motor at a slow speed and the HIGH/LOW switch selects between high and low speed. The high spped is ramped and the slow speed is not. Unlike the OFM cards, the motor will only run when the switches are closed. Momentary switches are not used. All settings are dip switch adjustable with 64 acceleration levels, 16 high speed settings and 4 low speed settings. Maximum speed is 11kHz and maximum acceleration time is 1355msec. |
 |
FFM04 The FFM04 is an osscilator that operates with START and STOP inputs like the OFM40, except that ramping is included. When the START input is pulled low momentarily the motor will start to accelerate from a set minimum speed to a set maximum speed and when the STOP input is pulled low momentarily the motor will decelerate befoe stopping. All settings are dip switch adjustable with 64 acceleration levels, 16 high speed settings and 4 low speed settings. Maximum speed is 11kHz and maximum acceleration time is 400msec. |
 |
FFM05 The FFM05 is ramped osscilator that produces pulses for a trapezoidal profile of known distance. When the START input is pulled low momentarily the motor will start to accelerate from a set minimum speed to a set maximum speed, travel at plateau velocity and then decelerate to a stop. The total number of steps output, speeds and acceleration are all set by dip switches. This is an ideal card for simple rotary indexing machines. Maximum speed is 11kHz and maximum acceleration time is 400msec. Maximum distance travelled is 65535 steps. |
 |
FFM01 The FFM01 is ramped osscilator that produces a pulse train when the START input is pulled low momentarily. The maximum speed is controlled by a potentiometer or an analog 0-7 V DC input rather than dip switches. This behaves like a voltage controlled osscilator and enables speed to be controlled from analog circuits. Maximum speed is 11kHz and maximum acceleration time is 400msec. |
 |
RMM36 The RMM is ramped osscilator that accepts a burst of unramped pulses at constant frequency and applies ramping to allow the motor to accelerate and decellerate without stalling. The output pulses start as soon as the first input pulse is received and a BUSY signal is provided when pulses are being output from the card. This is particularly useful when using computers or PLCs without ramping to control motors. Maximum acceleration time is 1270msec. |

RC10 The RC10 ramped clock card is designed to manulally control position when stepper motors are used on machine tools. There are 3 inputs from remote panel switches. START+ runs the motor at slow speed. START- runs the motor at slow speed in the reverse direction. When the FAST switch is pressed with either SLOW+ or SLOW- the speed is increaesd and ramping is applied. All speeds are set by on board or external potentiometers. To prevent overtravel, there are lalso imit switch inputs. Fast speed range (ramped) is 600-20000 kHz and slow speed range (non ramped) is 130-1000 Hz.
