ETEL DSCDL Dual Axis Controller Hardware Integration Guide

Pin 1: PE (protective ground, must be connected first! ）

Pin 2: GND (power ground)

Pin 3: V - (-36VDC, protected by F5 8A fuse)

Pin 4: V+(+36VDC, protected by F4 8A fuse)

Pin 5: VAUX (auxiliary power supply+15~+36VDC, protected by F3 1A fuse)

Main power requirements: ± 36VDC symmetrical power supply, with current requirements for each axis at full load as shown in the specification table. DSCDL331 has a maximum of 5A per axis, while DSCDL332 has a maximum of 10A per axis.

Auxiliary power requirements:+15~+36VDC, typical current of 1.5A (@ 15V) to 0.75A (@ 36V), used for controlling circuit power supply. Key: Even if the main power supply is disconnected, if the auxiliary power supply is maintained, DSCDL can still maintain encoder position counting and communication, achieving "hot standby".

Power outage safety: The manual emphasizes that after disconnecting the power supply, wait for 2 minutes for the internal DC bus capacitor to discharge before touching the connector. This time is shorter than high-power servo (usually 10 minutes), but it is still necessary to comply.

EMC Cable Shielding Specification

DSCDL has strict requirements for electromagnetic compatibility, and the following cables must use shielded wires:

Encoder cable (JC5/JC6)

I/O cable (JC12/JC13)

Communication cables (JC1~JC4)

Motor cables (JC8/JC9)

Power cable (JC10)

Shielding rules:

Use copper braided shielding (coverage ≥ 85%), and prohibit the use of cables with only aluminum foil shielding.

Connect both ends of the shielding layer 360 ° to the metal casing of the connector (using metal cable clamps).

Prohibit the use of "pig tail" (short lead) to connect the shielding layer - completely ineffective at high frequencies.

The connector must be a fully metal conductive shell.

The manual provides a schematic diagram of a good shielding connection: the shielding layer is clamped between the metal cable clamp and the connector housing after unfolding, ensuring 360 ° contact.

Axis number DIP switch setting

The axis number of the DSCDL dual axis controller is set through DIP switches (4 bits) according to the following rules:

Axis number=DIP switch binary value x 2

The first axis is the value multiplied by 2, and the second axis automatically increases by 1

Example: DIP switch 3 (binary 0011) → first axis=6, second axis=7.

Special case: When all switches are turned to "1" (high position), the controller reads the axis number previously saved through the AXI command (if not saved, it defaults to axis 1 and 2).

When multiple DSCDLs share TEB, the axis number of each controller must be unique and continuous (such as axis 0/1, 2/3, 4/5...), otherwise "BAD NOTE TEB ERR" will appear.

LED status indicator diagnosis

DSCDL provides multiple sets of LEDs for quick on-site status assessment:

Meaning of LED status

Green "TEB OK" is always on, and TEB communication is normal

Turn off TEB communication interruption (check cables or main station)

The green "SERVO ON" constant light controller has no errors

The controller has an error or is not turned on when extinguishing

The red (universal) constant light controller has an error (check M64)

Red "ERROR M1" constantly on, motor 1 has an error

Green "POWER ON M1" constantly on, motor 1 has been powered on

Attention: ERROR and the corresponding axis's POWER ON LED cannot be lit simultaneously (except during the startup phase). If they are lit simultaneously, it is considered abnormal.

Quick troubleshooting table for on-site hardware failures

Possible causes of malfunction, inspection methods, and solutions

SERVO ON does not light up after power on. Auxiliary power supply is missing. Measure the voltage at pin 5 of JC10 and check the auxiliary power supply and F3 fuse

TEB OK does not light up. If the TEB cable is disconnected or the main station is not running, check the CAT5 cable and DSMAX and unplug them again. Check the status of the main station

Single axis unable to power on, corresponding motor not connected or F4/F5 blown. Check JC8/JC9 connections, replace fuses, and inspect motor cables

Abnormal encoder reading, poor shielding or long cable. Check the shielding layer connection and reprocess the 360 ° shielding grounding

Two axes interfere with each other. The encoder cable runs parallel and is too long. Check the wiring layout and separate the power and signal lines

Zero return failure DIN2 (Home) signal not connected or level incorrect. Measure the voltage at pin 2 of JC12/JC13 and check the external switch and power supply

Analog input invalid AIN ± wiring reverse measurement JC7 pin 2/3 or 4/5 polarity calibration

Inappropriate positioning error encoder interpolation parameters K77 or K69. Check M241 value and adjust K77 (analog) or K69 (TTL)
