Daughter BoardsVarious Boards for Previous Generation Motion Coordinators

Daughter Boards provide the interface to many types of Servo or Stepper Axes, plus a number of advanced communications options as well.

The number of daughter boards which may be fitted is dependant on the controller type.

The MC224 master units can hold up to 4 daughter boards in any combination. Up to 12 further daughter boards can be connected using optional Axis Expander units (4 daughter boards per unit). Communication Daughter Boards P225, P291, P292, P293, P295, P296, P297 and P298 can only be fitted in the master unit.

The Euro 205x and Euro 209 has a single daughter board slot which can be used to provide extra axes on board.

The MC206X can use a single daughter board to provide a sixth axis in addition to the five axes (maximum) which are available on the standard controller.

The MC4xx range of Motion Coordinators does not use the daughter board concept.

Enhanced Servo Encoder (P201)

The servo encoder daughter board provides the interface hardware for a single analogue servo drive. The board provides a +/-10Volt analogue output for controlling most servo drives, and an interface for incremental encoders with hardware registration latch.

Servo Resolver (P210)

The servo resolver daughter board provides the interface hardware for a single analogue servo axis with absolute position feedback from a resolver. The board provides a +/-10Volt analogue output for controlling most servo drives, and an interface for direct connection to a resolver for position feedback.

Note: Most servo motors fitted with resolvers take the resolver signals into the servo drive. The drive then generates psuedo incremental encoder pulses and these signals are fed to the Motion Coordinator. The P210 is NOT required in these circumstances. Use a P200 or P201 servo encoder daughter board instead

Reference Encoder (P220)

The encoder daughter board provides an encoder input without a servo control facility for measurement, registration and synchronization functions on conveyors, drums, flying shears, etc. The encoder port is fitted with high speed differential line-receiver inputs.

The encoder daughter board provides a hardware position capture function for both the encoder Z input and the dedicated 24 Volt registration input. Transitions of either polarity on both these inputs can be used to record the position of the axis at the time of the event within less than 1 micro second. This allows event positions to be captured with very high accuracy for use when coordinating motor axes together.

Precision Analogue Input (P225)

Trio, a pioneer in the use of modular option daughter boards, adds the P225 to the line up. The P225 provides (8) 16-bit analogue input channels for general-purpose use in the range of 0-10Vdc. analogue inputs are available using the CAN analogue Module (P326) via the CANbus link, or using the P225 for faster updates and more resolution.

With the P225, users can get all channels of analogue data synchronized to the servo loop at 250us. With the addition of a "remote axis" FEC, the P225 can be used to close the servo loop using an absolute voltage for feedback. For example, a two axis analogue / servo system would require a P225 and P702

. The P225 is ideal for applications requiring precision torque or force control from an analogue transducer. If an unused encoder input is available on the Motion Coordinator, incremental position feedback can also be fed back to the controller for verification of a torque-force axis.

The 16-bit resolution and high-speed servo-loop synchronization can give performance previously unattainable in low-cost motion controllers.

Stepper Encoder (P240)

The stepper daughter board with position verification has all the features of the standard stepper daughter board. Position verification is added to a stepper axis by providing encoder feedback to check the position of the motor.

An encoder port on the daughter board allows the position of the motor to be checked on every servo cycle. If the difference between the demanded number of steps and the measured position exceeds the programmed limit, the Motion Coordinator can take undertake a programmed error sequence.

Hardware Pswitch (P242)

The hardware PSWITCH daughter board allows 4 open-collector outputs to be switched ON and OFF at programmed positions. This function is similar to the software PSWITCH command which is implemented in the system software and allows outputs to be switched ON and OFF over position sectors. The Hardware PSWITCH daughter board performs the position comparison in electronics hardware on the daughter board. This allows the generated pulses to be very accurately timed.

SSI Absolute Servo (P270)

The SSI daughter board provides the interface to a DC or Brushless servo motor fitted with an absolute SSI Gray Code encoder or encoder emulation. The encoder port provides high speed differential synchronous serial interface (SSI). This port is opto-isolated to maximise the noise immunity of the system.

The SSI port is programmable so that any number of bits from 1 to 24 can be clocked into the position registers. If the registration function is to be used then a minimum of 12 bits is required for correct operation.

The SSI daughter board provides a hardware position capture function for both a 5V differential input and a dedicated 24Volt registration input. Transitions of either polarity on both these inputs can be used to record the position of the axis at the time of the event within less than 1 micro seconds. This practically eliminates time delays and avoids interrupting the processor frequently in multi-axis systems. It should be noted however that the SSI system overall does not support this level of accuracy due to delays in clocking data from the encoders. The servo daughter board provides a 12 bit +/-10V voltage output to drive most servo-amplifiers. The voltage output is opto-isolated as standard to maximise the noise immunity of the system.

On the MC224 Motion Coordinator, multiple sercos daughter boards can be used to provide up to its maximum of 24 axes.

Servo drives from a wide variety of sercos compatible manufacturers can be connected via the fibre optic ring. The Motion Coordinator software allows for configuration of the servo drives, reading and writing drive parameters, and running cyclically in speed or position modes.

Each P291 fitted in a Motion Coordinator allows the use of 2 sercos axes. Additional axes can be enabled using “Feature Enable Codes”.
