Lenze 13466187 EDBTL03 v8 EN, DE, FR, IT, ES
Cause
Trouble free operation
LOW signal at terminal 28
Controller is set up for remote
keypad (see C01)
Quick stop activated through digital
input
c42 = 2, 3
DC-injection brake activated
• via digital input
• automatically
c48 = 1 and terminal 28 = HIGH
Controllable overload
Mains voltage too low
Excessively short deceleration time
(C13, c03)
Can only be changed when the control-
ler is in OFF or 1nh
Attempt to use buttons on front of
controller
Cause
C93 value stored on EPM does not
match controller model
Data not valid for controller
Data error
OEM data not valid
c42 = 0, 2
EPM missing or defective
E1...E3 assigned with the same digital
signals
Either just "UP" or "DOWN" used
Dynamic braking resistors are
overheating
Digital input "TRIP set" is active
Remedy
Set terminal 28 to HIGH
Start the controller via the remote
keypad
Deactivate Quick stop
Deactivate DC-injection brake
• digital input = LOW
• automatically after holding time c06
has expired
Only perform the motor calibration
when C14 = 4...7
Automatically (see C22)
Check mains voltage
Automatically if overvoltage
< 1 s, , if overvoltage > 1 s
OU
Set terminal 28 to LOW
Buttons on front of controller are dis-
abled when remote keypad is active
(1)
Remedy
Please contact Lenze
• Use EPM providing valid data
• Load Lenze setting
LOW-HIGH signal change at terminal 28
Power down and replace EPM
Each digital signal can only be used
once
Assign the missing digital signal to a
second terminal
Increase deceleration time
Remove external error
Please contact Lenze
