KL8001 Power terminal - Functional description

Rotary switches for adjusting the rated current

You can set the motor's rated current manually using the two rotary switches on the power terminal. The upper rotary switch operates in 1 A steps, while the lower switch provides 0.1 A steps. You can thus set values between 0.9 A and 9.9 A. The value set then applies to all three phases.

If you set the two rotary switches to zero, you must specify the rated motor current using the three parameter registers PR33, PR39 and PR45. You can then:

KL8001 - LEDs

The power terminal has 4 LEDs for status display to enable rapid diagnosis. The possible states are listed in the following table.

LED

State

Description

on (motor)

on

Motor is running, either to the right or left

off

Motor is switched off, or overload protection has triggered

overload (motor)

on

Motor has been switched off due to overload

flashes (2 Hz)

Power has fallen below minimum load threshold

flashes (5 Hz)

Overload threshold has been exceeded

off

Nominal operation (load neither below minimum and or above maximum), or motor is switched off

run (fieldbus)

on

Communication with the terminal bus is taking place without errors

off

No communication with the terminal bus (watchdog timer has triggered after 100 ms)

stop (fieldbus)

on

No communication with the terminal bus

flashes

Error code and error argument are indicated as flashing code

off

Communication with the terminal bus is taking place without errors

Flashing Code

If there is a fieldbus error, the stop LED indicates a flashing code that describes the fault more accurately:

The LED flickers for about 2 seconds before starting the error output. After a clearly visible pause, the error code is indicated through slow flashing, and the error argument is then indicated after a further pause. The following table allows you to determine the error more precisely with the aid of these two items of information.

Code

Argument

Description

Solution

1

0

No rated current set: both the two rotary switches and

  • the register PR33 are zero (single-phase analysis not active) or
  • at least one of registers PR33, PR39 or PR45 is zero (single-phase analysis is active)

2

n

Communication with the nth ADC is faulty

Contact your supplier.

3

n

Communication with the nth Hall sensor is faulty

Changing the terminal registers

  • To ensure that the new values are applied to the measuring unit after the terminal registers have been changed, you have to perform:
  1. a power-off reset (switch the terminal off and back on again) or
  2. a software reset (via the command register)!
