ETEL DSB2P Series Servo Amplifier Connection and Configuration Guide

3.2 Simulated sine cosine encoder (J1, 9-pin D-Sub female socket)

The analog encoder outputs sine and cosine signals (with a phase difference of 90 °), which can provide higher resolution position information. DSB2P supports two types of signal amplitudes:

1Vptp (peak to peak value 1V): Model identification is DSB2P1xx xxxE

11 μ Aptp (peak to peak value of 11 μ A): Model identification is DSB2P2xx xxxE

The hardware circuits of the two models are different and cannot be interchanged. Pin definition:

1: SIN - (Negative Terminal of Sinusoidal Signal)

2：GND

3: COS - (cosine signal negative terminal)

4：GND

5: IDX - (Zero Position Signal Negative Terminal)

6: SIN+(sine signal positive terminal)

7: +5V (protected by F7 500mA)

8: COS+(cosine signal positive terminal)

9: IDX+(positive terminal of zero position signal)

Shielding requirement: The analog encoder signal has a small amplitude and is highly susceptible to electromagnetic interference, requiring the use of double shielded cables. The outer shielding layer is connected to the connector housing at both ends (360 ° ring connection), and the inner shielding layer is only connected to GND at the driver end to avoid ground loops.

3.3 Digital Hall Sensor and Temperature Protection (J9, 9-pin D-Sub Male Head)

J9 provides three digital Hall signal inputs (H1, H2, H3) and motor overheat protection input (PTC/temperature control switch). Pin definition:

1: +Text (external power input for Hall and PTC)

2: H1- (Hall sensor 1 input)

3: H2- (Hall sensor 2 input)

4: H3- (Hall sensor 3 input)

5：GND

6: TS - (PTC or temperature control switch input)

7: +5V (protected by F7)

8: +15V (protected by F3 250mA and shared with J2 auxiliary power supply)

9：GND

Hall signal wiring: Three Hall signals correspond to the position information required for three-phase motor commutation, and their timing relationship corresponds to the motor phase voltage. The manual provides a standard connection diagram. For ETEL motors, the PTC trigger temperature is usually 100 ℃ (ILx series) or 120 ℃ (LMx/TMx series). When this temperature is exceeded, the TS input is pulled low and the driver reports a "MOTOR OVERTEMP" error.

User I/O connection (J2, 15 pin D-Sub male)

J2 provides analog input, 6 digital inputs, 3 digital outputs, and auxiliary power supply.

4.1 Analog Input (AIN1)

Pin 2 (AIN1+) and Pin 9 (AIN1-)

Input range: ± 10V, 14 bit resolution (AD7863)

High input impedance, can be directly connected to the analog output of PLC or motion controller.

4.2 Digital inputs (DIN1-4, DIN9, DIN10)

Using optocoupler isolation, the input voltage range of+15~+28V corresponds to logic "1", and 0V corresponds to logic "0".

Function allocation (configured by software): DIN10 is usually used as a positive limit switch, DIN9 as a negative limit switch, and DIN2 as a home switch.

External power supply can be provided by an independent power supply (pin 11 is+Voxt, pin 3 is GNDext), or by a+15V auxiliary power supply provided by the driver (pin 10), but using an auxiliary power supply will lose the advantage of optocoupler isolation.

4.3 Digital outputs (DOUT1~3)

Optocoupler isolation, open collector output. External pull-up resistor or load power supply (+Text, pin 11) is required, with a maximum voltage of 28V.

Typical applications: outputting servo readiness signals, limit trigger signals, or fault alarm signals.

4.4 Auxiliary power output

Pin 10 provides+15V/250mA (protected by F3), which can be used to power external sensors or Hall encoders, but it should be noted that the total current does not exceed 250mA (shared with J9's+15V).

Communication interface wiring (J3~J6)

5.1 ETEL-Bus（J3/J4，RJ45）

J3 is the EB output (connected to J4 of the next level driver), and J4 is the EB input (from the previous level driver).

Default RS422 differential communication, speed 460000bps, supports up to 32 daisy chain drives.

If you need to use RS232 type EB (115200bps), you need to short-circuit pin 1 (EB_delect_422/232) of J6 to GND.

5.2 ETEL-Bus-Lite（J5，RJ45）

Used for debugging communication between PC and driver (ETEL Tools software).

Supports RS232 (pins 6/7) and RS422 (pins 2-5), default RS422. If RS232 is required, short pin 1 (EBL_select_422/232) to GND.

Serial port parameters: 9600~115200bps, 8 data bits, 1 stop bit, no checksum, no flow control.

5.3 Download key interface (J6, RJ45)

For firmware upgrade: Insert a dedicated download button (pin 4-8 short circuited, 5-2 short circuited), power on the drive and enter the "Wait for Program" mode to download new firmware through the RS232 serial port.

Motor and power wiring (J7/J7B/J11/J14/J15)

6.1 Motor Connection (J7/J7B)

J7 is a standard 5-pin high-power D-Sub that supports single-phase (using only PH1 and PH2), two-phase (PH1/PH2/PH3/PH4), and three-phase (PH1/PH2/PH3) motors.

J7B is a motor interface with a short-circuit relay option (only versions with suffix 4 and sub models including 2). During normal operation, the relay contacts are open, and during faults or emergency stops, the contacts are closed. The motor is short circuited in three phases to achieve dynamic braking.

6.2 DC power input (J11, rack module)
