EEL-S2-2

Linear actuator controllers

Afmetingen

 EEL-S2-2

  • driven by two actuators

  • synchronised parallel drive
  • Hall sensors required
  • suitable for all actuators

  

   

The S2-2 offers advanced positioning and control of actuators by means of a simple yet flexible integration with the application. The controls have been developed for control of our actuators that require position determining. S2-2 has adjustable acceleration and deceleration ‘ramps’, which make a smooth start/stop possible.

Adjustable current limits in both directions protect the motor against excess current. In the 'learning' mode, the number of pulses for a complete stroke are counted. This ensures accurate positioning during normal use.

The position of the actuator is determined by a DC voltage between 0-5 or 0-10 Volt to the S2-2.

Adjustments and parameter settings such as current limit, ramp times, speed etc. can be set using the S2-PROG interface or the S2-USB dongle connected to a PC.

Technische informatie

  1. Power supply for Hall sensors (+5 V output)
  2. Hall channel A
  3. Hall channel B
  4. GND (0V)
  5. Actuator -
  6. Actuator +
  7. Power supply 12-24 VDC (use fuse)
  8. GND (0V)
  9. Position OK - digital output 5 V through 1 kOhm when desired position is reached, and low during movement 
    Note: when the 'brake zone' is long, it can be difficult to reach the 'Position OK' signal because the motor has too little power within the 'dead zone'.
  10. Memorising - digital input (>4 V and max. supply voltage) start 'memorising'. Rin 47 K.
  11. Stop/Rest - digital input (>4 V and max. supply voltage) stops motors and resets every error. Rin 47 K.
  12. Pos. setting - analogue input 0 - 10 V (0 - 5V if and max. supply voltage) start 'memorising'. Rin 47 K.
  13. Error IN/OUT - NPN open collector max. 100 mA can be connected to other C2-20 modules. If one of the modules sends an error signal, all modules will stop. When the cable length is longer than 1 metre, a 10 kOhm pull-up resistor connected to a power supply is recommended.
  14. +5,4 V output, maximum of 10 mA

Circuit diagram

Wiring and settings

First perform a memorise cycle and then set settings with the serial interface unit ' S2-PROG' or a PC. Standard values in ()

1/15 Speed35 - 100% <=> 35-100 ( 100 )

2/15 Memorise cycle speed: 35 - 100% <=> 35-100 ( 50 )

3/15 I-limit "forward": 0.1 - 20.0A <=> 1-200 ( 20 )

4/15 I-limit "reverse": 0.1 - 20.0A <=> 1-200 ( 20 )

Note: Current limit is 1.5 x higher during start ramp and 1 sec. afterwards.

5/15 I-trip enable: 0/1 <=> off/on ( 1 )

6/15 I-trip delay: 0 - 255ms <=> 0 - 255 ( 5 )

7/15 Load compensation: 0 -255 <=> 0 - 255 ( 0 )

8/15 Pulse lost timeout: 1 - 5s <=> 1 - 5 ( 2 )

9/15 Start value: 0 - 50% <=> 0 - 50 ( 30 )

10/15 Hour/Start count rest: 0 - 1, reset is at 1

11/15 Brake area: 0.0 - 20.0% <=> 0 - 200 (50)

12/15 Dead zone: 0.0 - 10.0% <=> 0 - 100 (10)

13/15 Range scale in: + 0.0 - 50.0% <=> 0 - 500 ( 7 )

14/15 Range scale out: - 0.0 - 50.0% <=> 0 - 500 (70)

15/15 Start ramp: 0,1 - 5s <=> 0 - 500 ( 100 )

Speed limits the maximum speed.

Memorise cycle speed determines the speed of the memorise cycle.

I-limit is individual for both directions.

I-trip ensures trip function, so that the motor stops when the I-limit is reached. Motor must be started in opposite direction after trip.

I-trip delay defines the reaction time for trip.

Load compensation increases the torque at low speed. Note that overcompensation causes oscillation and shaking of the motor.

Pulse lost timeout stops the motor after set time without pulse.

Start value is a voltage level before start (% van vol), this ensures the motor has an adequate voltage to start correctly. However, note that a too high starting level causes vibration of the motor.

Hour/Start count reset makes it possible to set the hour/start counter to ‘0’.

Brake area (soft-stop) is a proportional value of the full stroke. In low speed applications, a good value is close to 1%. In high speed applications, a value of close to 20% can be selected.

Dead zone is a stable zone, suitable size of the zone is dependent on the mechanical accuracy of the system, this value is also a ratio of the full stroke length (%).

Range scale setting is for scaling the stroke, after memorise cycle the scale can be adjusted. The inputs and outputs can be scaled individually in order to realise a suitable mechanical stroke with a value of 0 – 10 V (0 – 5 V).

Start ramp (soft-start) defines the time before full speed is reached.

Status LED signals

Positioning window

  1. Rapid flashing = Stopped because current limit is active
  2. Slow flashing = Overtemperature
  3. Slow flashing = Overtemperature
  4. Short, medium, long… = Hall pulse lost
  5. 4 x rapid flashing, pause = overvoltage
  6. 2 x short, 1 x long = Error in
  7. LED permanently on = Memorise cycle not complete, new cycle required

Learning cycle

  1. Start learning by giving an impulse to learn input (10)
  2. Motor starts to run “out” direction with learn speed
  3. Current limit stops the motor when mechanical end is reached
  4. Motor starts to “in” direction and makes a full stroke. During stroke the pulse counter measures the range.
  5. Motor reaches the mechanical end “in”, and current limit stops the motor.
  6. Device stores full range value and is ready for use

Range scaling

  1. Original memorised range = mechanical complete range = signal range 0 – 10 V (0 – 5 V)

  2. Modified range example: If range scale in = +20% and range scale out = -20%; then stroke of the actuator is set to: position set value 0 V = 20% position; position set value 10 V (5 V) = 80% position

Warnings and recommendations

  • If S2-2 goes into ‘trip’ (excess current), only movement in the opposite direction is possible.
  • Set the maximum current 10% higher than the maximum current while the motor is running. This ensures the best conditions for a longer service life of the motor, actuator, mechanics, and electronics.
  • It is important to make sure that the power supply provides sufficient power to the control board. If this is not the case, the controller and actuator may be damaged.
  • Double check the correct polarity of the power supply. If connected incorrectly, the S2-2 will be damaged.
  • Attention! S2-20 has no fuse. Depending on the application, use an external fuse (2 > 10 A slow)
