PD-170_1

PD-170 57mm BLDC Motor with Intelligent Electronics and Serial Interface The PD-170-57 is a full mechatronic solution including a 57mm brushless DC motor (NEMA23). It combines a convenient servo controller electronic (TMCM-170) and an optical encoder with different motor types. The PD-170-57 offers two motor torque options and can be controlled via RS232, RS485 and/or CAN interface. The power supply can be connected via screw connectors and the interface and the multi-purpose I/Os can be connected via high density JST connectors. This PANdrive combines the high resolution commonly known from stepper motors with the high dynamic, high velocity and high reliability of a BLDC drive. It integrates a position regulator and a ramp generator. The ramp generators supports parameterized smooth positioning also with an external switch in order to support an absolute position reference. Features: Connectors: At the PANdrive 170 the motor, encoder and hall sensor connections are already done. The I/O-board has to be detached to access the screw connectors for power supply. 1 2 3 4 5 I/O 6 7 1 8 2 3 1 4 In 25 te 3 r 4 Encoder fac e 5 Driver board (top view) I/O board (top view) Interface I/O Hall Enc Motor Power UVW + 1 Hall 2 sensors 3 4 5 Motor Power Interface Pin 1 2 3 4 5 I/O Pin 1 2 3 4 5 6 7 8 Name AIN N.C. /STOP DIRIN OVT GND CUR +5V Function CANH CANL Ground RS485+ / RxD Rs485- / TxD Encoder Pin 1 2 3 4 5 Function +5V supply Ground Channel N / Null channel Channel A Channel B Power supply Function Analog input: 0 - 10V signal.

TMCM-170 Software: 1. 2. Choose a COM port and click “Open”. With established connection the module´s type and version as well as parameters like supply voltage, current and module temperature are displayed. The preconfigured values (for setup (1) and (2) also) stored in the EEPROM of the TMCM-170 can be displayed by clicking button “Read Back” in Settings section. Do not exceed a current of maximum 10 A. At Section Motor Control type in a velocity like “1000” and click “Left” or “Right”. Stop the motor by clicking “Stop”. Type in a position and let the motor move to the absolute position or relative to actual position (see position counter on the right). For more functions and explanations read the TMCM-170 hardware and programming manual. For full functionality use the TMCL-IDE at TechLibCD. 3. 4. 5. 6. For full functionality of the TMCM-170 use the TMCL-IDE. All commands can be included into a program or used in “Direct Mode”. There are e.g. motion (ROR, ROL, MST, MVP) and SAP (Set Axis Parameter) commands to set motion and control parameters. GAP delivers their actual value. Instr.

TMCL-IDE: CAUTION: For short moves do not exceed a max. current (SAP 6) of 14A (value 180). 10A (value 138) is recommended as maximum for constant rotations. Troubleshooting: • • • • If communication is not established: Check if the power LED (green) of the TMCM-170 lights. If not check your power supply. Check if you are using the right COM port and it is not blocked by another program. Check your interface connection. Are you really using a null modem cable? Refer to TMCM-170 manual or Trinamic support forum for further information and help. If the motors do not respond: • Usually it is a problem with the communication described above. • If the current limit LED (center) is flashing or on (red) the voltage or current are too low. • Set a value for current limit, e.g. 6.0A and apply this value. • Read back and check the values of the module by pressing button read back. • Is the temperature limit exceeded? Indicated by red LED. Blink: pre-warning, On: motor stopped. • Switch power off, wait a few seconds and switch on again, to reset all unstored parameters to factory defaults.
