ETEL DSB2P Series Servo Amplifier Connection and Configuration Guide

15 pin DIN41612 connector, key signal:

Z20/d22:+VPWR (main power supply 24-340VDC)

Z16/d18/d26: GNDpwr (power ground)

Z12:+V/AUX (auxiliary power supply, 24-55VDC or 96-340VDC, depending on the sub model)

Z24: GNDaux (auxiliary ground)

D14: INRISH (surge signal from power supply, 0V=OK,+15V=charging in progress)

Z28/d30: PE (protective grounding, must be connected first! ）

Important: If using a non ETEL power supply, d14 (INRISH) and d18 (GNDpwr) must be short circuited, otherwise the drive cannot enter normal operation mode.

6.3 AC power input (J14/J13, integrated power module)

J14 (3-pin) is the main power input, connected to 85-240Vac single-phase or three-phase AC power.

J13 (2-pin) is an auxiliary power input, also 85-240Vac.

Attention: It is recommended to install an external isolation transformer at the power input end to meet CE/EMC requirements, and configure a circuit breaker to urgently cut off the motor power without losing encoder position data (maintaining auxiliary power).

6.4 External regeneration resistor (J12, 2-pin)

Only suffix 4 modules are supported, with pins R+and R - connected to external regenerative resistors.

The minimum resistance of the resistor is 39 Ω, and the power is not less than 3.8kW (@ 380Vdc) to protect the internal regeneration transistor.

EMC cable shielding and grounding

DSB2P, as a PWM chopper amplifier, generates strong electromagnetic interference during operation. Section 3.7 of the manual provides strict EMC wiring requirements that must be followed during on-site wiring.

7.1 Lines that must use shielded cables

Motor cable (J7/J7B): high di/dt circuit, strong radiation source.

Encoder cable (J1/J9/J10): weak signal, highly susceptible to interference. The analog encoder (11 μ Aptp) requires double shielded cables.

7.2 Shielding Layer Connection Specification

Single shielded cable: The shielding layer is connected to the connector housing at both ends (360 ° ring connection).

Double shielded cable: The outer shielding layer is connected to the outer shell at both ends, and the inner shielding layer is only connected to GND at one end (driver end).

It is prohibited to use "pig tail" (short lead) to connect the shielding layer - this connection method is completely ineffective at high frequencies and must use cable clamps with 360 ° ring contact.

7.3 Cable Routing Principles

Power cables and signal cables should be routed separately to avoid parallel long-distance laying.

All cables should be as short as possible and fixed to the metal bottom plate of the cabinet using cable clamps.

If there is an intermediate connector along the shielded cable, its casing must be insulated and not in contact with each other to prevent the formation of a ground loop.

Short circuit relay configuration and application (DSB2Pxx4-2xx)

Short circuit relay is an optional safety function of the integrated power module, used to quickly brake the motor in case of emergency stop or driver failure.

Working principle: The normally closed contacts of the relay are connected in series in the three-phase circuit of the motor. During normal operation, the driver applies a+24V power supply through pins 3-4 to energize the relay coil, causing the contacts to open and the motor to run normally; In case of emergency stop or malfunction, cut off the coil power supply, close the contacts, cause a three-phase short circuit in the motor, and generate braking torque.

Recommended Control Circuit:

Connect the normally closed contacts of the emergency stop button in series with the relay coil power supply circuit.

Simultaneously configure DIN1 as a safety enabled input (K33=0), and the driver will automatically shut down the power bridge when DIN1=0V.

Program DOUT1 as a fault output (K37=1), with DOUT1=0V in case of a fault, which can be used to disconnect relay coils or notify the upper computer simultaneously.

External power supply requirements: The relay coil must have an independent+24V external power supply and must not be grounded with the internal power supply of the driver to ensure that braking can still be performed even when the driver is completely powered off.

Quick troubleshooting table for on-site hardware failures

Possible causes of malfunction, inspection methods, and solutions

Power on, no display. Auxiliary power supply not connected or fuse F3/F7 blown. Measure J11/J15 auxiliary voltage. Check auxiliary power supply and fuse

The motor does not rotate and there is no current. The INRISH signal is not connected correctly. Measure d14 and short-circuit d14 to ground voltage (non ETEL power supply)

Encoder reading jumps, shielding layer not grounded 360 ° or cable too long. Check shielding connection and reprocess cable shielding

Frequent overcurrent alarm of the driver, poor shielding of the motor cable or incorrect phase sequence of the motor. Check K56 and cable, execute AUT command or exchange phase lines

Zero return repeatability difference Hall signal or encoder zero position signal interference oscilloscope inspection signal quality enhancement shielding, check J9 wiring
