  • Page 20: Hardware Setup

    There are several 3 contact male pin headers on the board with a jumper either occupying the center and left pins (position A) or the center and right pins (position B). Below is a list of jumper settings for the EC 2000. All jumpers not listed should be left in the default position.

  • Page 21: Table 2: Follower Setpoint Jumper Settings

    8 – 40 mA (DC) • To properly utilize motor torque limiting with the EC 2000, the red dip switch “SW1” must be set in conjunction with a current transformer. Below is a table with “SW1” contact configurations with Dynamatic® approved current transformers.

  • Page 22: Section 6 - Keypad

    SECTION 6 – KEYPAD • The EC 2000 can be either controlled via the keypad or from external pilot device, but initial programming must be done with the keypad. • The keypad is plugged into the “PL2-KEYPAD” male pin header on 15-1200-1.

  • Page 23: Section 7 - Programming

    SECTION 7 – PROGRAMMING Menu A: Control Setup 1. CONTROL TYPE • Speed (default) o Uses the AC Tachometer Feedback for speed feedback and control. • Torque o Clutch coil voltage is regulated. This is frequently used for take-up or spooler applications where torque is proportional to tension and speed varies with the diameter of the roll.
  • Page 24 6. TORQ PULSES/REV Sets an alternate pulses per revolution rate (PPR) for applications that use more than one transducer. To enable this rate, enable Menu A. Parameter 18 and close TB2-25. 7. CLUTCH MIN RPM The minimum speed for the clutch. 8.
  • Page 25 (Default: 0). 15. SPEED FILTER CLAMP Limits the amount of speed feedback readings done by the EC 2000. This is primarily used for non-standard speed feedback configurations, noise affected configurations, or heavy loads not getting up to speed in a timely manner (Default: 0).
  • Page 26 Used to adjust the difference between the actual clutch current (measured with a DC clamp on meter) and the current reading of the EC 2000. If the keypad displayed clutch current is less than measured, increase the percentage, and vice-versa (Default: 100%).
  • Page 27 26. CONTRLR BAUD RATE Changes the BAUD rate (how fast data is sent over a serial line) of the control data transfer. • 4800 • 9600 (default) • 19200 • 38400 27. DATA XMIT ENABLE Allows the user to enable or disable data transmission. •...

  • Page 28: Menu B: Clch Performance

    Default: 0% 7. ENABLE CURRENT LOOP The EC 2000 has two PID loops (as seen in the previous parameters), speed and current, where the speed PID loop is fed into the current PID loop. This parameter allows the user to disable the current PID loop.

  • Page 29: Menu C: Accel/Decel Setup

    Allows to user to adjust the brake output (TB1 – B1/B2). Note, the brake will enable when the clutch drops out. For simultaneous clutch and brake output, a “Mutuatrol” modification is required (please consult Dynamatic). 1. Brake Coil Rating Enter the brake current rating found on the nameplate.

  • Page 30: Menu E: Follower Setup

    If the follower signal is lost or drops below a certain value due to an external failure, the user can program the EC 2000 to run at a specific speed. This parameter allows the user to set the level at which to activate this.

  • Page 31: Menu F: Analog Outputs

    Menu F: ANALOG OUTPUTS The EC 2000 can output two different analog values based on a variety of statuses or setpoints. Note that for a 4-20mA or 8-40mA output, proper programming and a 500 Ohm resistor should be connected (See Figure 10).

  • Page 32: Menu G: Relay Output

    Menu G: RELAY OUTPUT 1. F RELAY The F Relay corresponds to TB1- F1/F2/F3 (see Figure 7). Trip ON means the relay is normally deenergized, TRIP OFF means the relay is normally energized. TRIP ON and TRIP OFF have the same options. •...

  • Page 33: Menu H: Units

    Menu H: UNITS 1. PROCESS UNITS • RPM (default) • PERCENT (used for torque mode) • USER USER can be selected to display speed in something other than RPM. If chosen, Parameters 2-4 are opened for changing. If not, Parameter 1 is the only one that is open. 2.

  • Page 37 7. COIL OPEN FLT EN If enabled, the control will fault if there is no detected clutch current when the output voltage is applied. • ENABLE (default) • DISABLE 8. SPD FDBK FLT EN If enabled, the control will fault if there is no detected speed feedback signal (ie AC Tachometer Generator) when the control is trying to run at a set speed.
  • Page 38 14. UNDERSP FLT EN If enabled, the control will fault if the speed set by parameter 10: UNDERSPEED TRIP is reached. • ENABLE • DISABLE (default) 15. UNDSPD FLT ACTION • RUN (keeps running if an overspeed occurs) • STOP (stops if an overspeed occurs) 16.

  • Page 39: Menu N: Auto Restart

    7.13 Menu N: AUTO RESTART 1. RESTART POWER EN If enabled, the control will start and enter run mode right after power is applied. • ENABLE • DISABLE (default) 2. RESTART FAULT EN If enabled, the control will restart and enter run mode again after a fault. •...

  • Page 40: Section 8- Troubleshooting

    • Disconnect the clutch coil leads from the EC 2000 (C1 and C2). Try to run the control with a setpoint and measure the DC voltage on the TB1-C1 and C2 (where the clutch coil leads were just connected).
