PD2-C-IP USB Online Manual: Pin assignment

Overview


Connection	Function
X1	Voltage supply
X2	Digital inputs and outputs
X3	Analog input and digital inputs
X4	Mini USB
S1	Hex coding switch for the special drive modes (clock-direction and analog speed)

Note: All pins with designation GND are internally connected.

X1 − voltage supply

Connection for the main supply. Type: M8, 3-pin, A-coded, male

Suitable Nanotec cable: ZK-M8-3-2M-1-AFF (not included in the scope of delivery)

Voltage source

The operating or supply voltage supplies a battery, a transformer with rectification and filtering, or a switching power supply.

Note:

EMC: For a DC power supply line longer than 30 m or when using the motor on a DC bus, additional interference-suppression and protection measures are necessary.
► An EMI filter is to be inserted in the DC supply line as close as possible to the controller/motor.
► Long data or supply lines are to be routed through ferrites.

Connections


Pin	Function	Note
1	+Ub	12-48 V, ±5%
3	GND
4	n.c.

Permissible operating voltage

The maximum operating voltage is 50.4 V DC. If the input voltage of the controller exceeds the threshold value set in 2034_h, the motor is switched off and an error triggered. Above the response threshold set in 4021_h:02_h, the integrated ballast circuit is activated (wirewound resistor Z32041412209K6C000 from Vishay with 3 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).

Note:

Damage to the controller and/or its power supply due to excitation voltage of the motor!
Voltage peaks during operation may damage the controller and possibly its power supply.
► Install suitable circuits (e.g., charging capacitor) that reduce voltage peaks.
► With BLDC motors: Select a voltage source that corresponds to the rated voltage of the respective motor as specified in the motor data sheet.
► Use a power supply with protection circuit to protect against overvoltage.

X2 – digital inputs and outputs

Connection for digital inputs and outputs. Type: M8, 5-pin, B-coded, male

Suitable Nanotec cable: ZK-M8-5-2M-1-PUR-S-F (not included in the scope of delivery)

Connections


Pin	Function	Note
1	GND
2	Digital input 1	24 V signal
3	Digital input 2	24 V signal
4	Digital output 1	Open drain, max. 24 V/100 mA
5	Digital output 2	Open drain, max. 24 V/100 mA

The following switching thresholds apply for inputs 1 to 2:


Max. Voltage	Switching thresholds (worst-case calculations)
Max. Voltage	On	Off
24 V	> 15.29 V	< 0.97 V

X3 – analog input and digital inputs

Connection for inputs and outputs. Type: M8, 8-pin, A-coded, male

Suitable Nanotec cable: ZK-M8-8-2M-1-PUR-S (not included in the scope of delivery)

Connections


Pin	Function	Note
1	GND
2	Analog input	10 bit, 0-10 V or 0-20 mA, switchable by means of software
3	-Release (-input 4)	The default setting for this input combination is "single-ended"; this means that the "-Release" input is deactivated, only "+Release" against GND is active. 5 V / 24 V signal, switchable by means of software with object 3240_h, max. 1 MHz
4	+Release (+input 4)
5	–Direction (–input 5)	The default setting for this input combination is "single-ended"; this means that the "-Direction" input is deactivated, only "+Direction" against GND is active. 5 V / 24 V signal, switchable by means of software with object 3240_h, max. 1 MHz
6	+Direction (+input 5)
7	–Clock (–input 6)	The default setting for this input combination is "single-ended"; this means that the "-Clock" input is deactivated, only "+Clock" against GND is active. 5 V / 24 V signal, switchable by means of software with object 3240_h, max. 1 MHz
8	+Clock (+input 6)

The following switching thresholds apply for inputs 4 to 6 (pins 3 to 8):


Max. Voltage	Switching thresholds (worst-case calculations)
Max. Voltage	On	Off
5 V	> 4.94 V	< 0.48 V
24 V	> 20.24 V	< 2.94 V

If you set 3240_h:07_h to the value "1", three differential inputs are available on pins 3 to 8. Where:


Switching on	Switching off
Voltage at input pin+ against GND > switch-on threshold	Voltage at input pin- against GND > switch-on threshold

X4 − Mini USB

A cable of type "mini USB" is needed for this USB connection.

S1 – hex coding switch for the special drive modes (clock-direction and analog speed)

You can use this switch to select one of the special drive modes.
