The CL3-E controller/drive has 5 V inputs. If a 24 V control signal is to be applied, it will require a 57 kOhm (0.25 W) resistor be connected in series to each input in use.
Note: For other controllers/drives with switchable 5 or 24 V digital inputs you can select which voltage range you want with object 3240 sub-index 6.
