X2 – encoder/Hall sensor
Two types of encoder/Hall sensor are supported:
- Encoder/Hall sensor with 5 V supply voltage. In this case, nothing is to be connected to X7; object 2059h must be set to the value "0" (factory setting).
- Encoder/Hall sensor with 24 V supply voltage. In this case, you must connect a voltage of 24 V DC to X7 (see X7 – voltage supply for encoder/Hall sensor, external logic supply) and set bit 0 in 2059h to "1".

Permissible operating voltage
Depending on the version, the maximum permissible voltage is:
- N5-1 (low current): 75 V DC
- N5-2 (high current) and up to hardware version w007: 51.5 V DC
- N5-2 (high current) and hardware version w007b and higher: 57.5 V DC. With this version, you must – if desired – enter the right threshold value in 2034h Upper Voltage Warning Level.
If the input voltage of the controller exceeds this threshold value, the motor is switched off and an error triggered. Above the response threshold set in 4021h:02h (but at the latest from 57.5 V), the integrated ballast circuit is activated (thick‑film resistor PWR163S-25-15R0J from Bourns with 25 W continuous output).
The minimum operating voltage is 11.4 V DC. If the input voltage of the controller falls below 10 V, the motor is switched off and an error triggered.
A charging capacitor of at least 4700 µF / 50 V (approx. 1000 µF per ampere rated current) must be connected in parallel to the supply voltage to avoid exceeding the permissible operating voltage (e.g., during braking).
X7 – voltage supply for encoder/Hall sensor, external logic supply
Functionality
- A 24 V encoder/Hall sensor is used. In this case, a voltage of 24 V DC must be connected to X7 and bit 0 in object 2059h set to the value "1".
- A logic voltage supply is necessary for the controller to ensure continued access to the following functions should the power supply be lost at connector X6 (see "X6 – voltage supply"):
- Logical functionality of the controller
- Controller communication
- Encoder
Note: The windings of the motor are not supplied by the logic supply.In this case, a voltage of 24 V DC must be connected to X7. With a 24 V encoder, bit 0 in object 2059h must be set to the value "1". In the case of a 5 V encoder, bit 0 in object 2059h is to be set to the value "0" (factory setting).Note:

S1 – hex coding switch for slave address and baud rate
Hex coding switch for setting the Modbus address and baud rate. See chapter Communication settings.
The value of this switch is multiplied by 16 and added to the value of switch S2; this switch thereby sets the 16s place.
S2 – hex coding switch for slave address and baud rate
Hex coding switch for setting the Modbus address and baud rate. See chapter Communication settings.
The value of this switch is added to the value of switch S1; this switch thereby sets the 1s place.
Example |
|
Switch S1 is set to the value "1h", switch S2 to the value "Fh"; the result is the value "1Fh". |
S3 – 150 ohm termination resistor
This DIP switch (pin 1, marked with an asterisk "*") switches the termination of 150 Ω between RS-485+ and RS-485- on or off.
