Calibration test for pulley/ internal rotation guard STP in the display no 5??
-
For example needed if received an E01 error/ alarm
If drive equipment is wired by us from factory and mounted in a RHE this test have been done before delivery
Before opening DRHX
, the mains voltage must be
disconnected for at least 3 minutes
to ensure that there
Is no risk of dangerous residual currents in electronic circuits or capacitors.
The test button you find to the right of the DIP switches, see figure 15.2 on page 7.
1. Turn off the DRHX controller and
remove the belt from the pulley.
2. Power up the DRHX controller and
briefly press
the test button, < 1 second, to start test mode
The LED will shine orange. Display will show "tSt" for test mode.
3. Wait for the stepper motor to reach maximum speed. It's limited to 100 rpm in this test.
4. After the stepper motor has reached the maximum speed, the system will start performing the internal rotor
guard function. The stepper motor will accelerate at short intervals every 10 seconds (that should be
possible to hear) for a minute.
5. If the stepper motor stops and restarts after one minute the internal rotor guard is correctly calibrated.
6.
Press the test button for 2 seconds to end test mode
. LED turn green. See point 8.
7. If the stepper motor continues to run for more than one minute, a recalibration needs to be done:
Recalibration
:
Press and keep pressing the test button
until LED flashes orange
( can take 10
–50 sec).
Remove your finger from the button and the LED will turn green, the pulley/ internal rotor guard has been
calibrated.
8. After, turn off the DRHX controller and mount the belt. Start normal operation procedure.
Alarms and fault codes
see table 19, page 10 and 19.1 page 11
DRHX has a built-in alarm monitor, which monitors optimal fault-free operation and triggers an alarm if operating
or performance problems are observed. Alarm codes can be read on the display.
Alarms are either ”Critical” or ”Non-
critical” alarms: ”Critical” alarms stop the stepper motor. ”Non-critical” alarms reduce stepper motor performance.
•
The built-in alarm monitor stops the DRHX.
•
If the alarm situation passes, the alarm is automatically reset and DRHX will be restarted.
•
If the maximum number of restarts (5 times/ 1 h) is overstepped, the
alarm must be reset
•
Alarm reset
:
The alarm is automatically reset if the power is disconnected for longer than 60 seconds.
or faul codes and alarm overview etc see table 19 and 19.1 in page 11
Remarks:
"C" = Critical alarm, stop the motor. / "NC" = Non-critical , reduce the motor performance.
”RP” = Reducing performance.
”SA5 ”= Stepper motor stops after 5 restarts caused by same fault within 60 min.
”S” = Stepper motor stops immediately
