SILVERPAK 23D/DE

Product catalog summary

Main Features:
The Silverpak 23D/DE motor and driver system operates with a voltage range of +15 to 48VDC and a current range of 0.3 to 3.0 Amps Peak, which is internally set and cannot be altered by the user. It features a hold current at 25% of the run current and offers multiple step resolutions (2x to 256x) adjustable via jumpers. The system includes damping modes (14% and 35%) to enhance motion smoothness and operates at a step frequency of 2.5MHz. Inputs include step pulses, direction change, and driver enable/disable functions. The integration of Pole Damping Technology (PDT) ensures smooth motion.

Pin Assignments:
The system uses a DB-9 connector with flying leads for power and control connections. Key pin functions include motor supply voltage, ground, step connection, disable/enable input, and direction change input. The internal +5VDC output can be used to power opto-isolated inputs.

Step Resolution and Damping Modes:
Step resolution is adjustable using jumpers, with settings ranging from 2x to 256x. Damping modes are provided to reduce resonance and vibration, with the most effective mode being motor-dependent.

Detailed Features:
Operating temperature ranges from 0 to 45°C, with a heat sink required above 2.6 Amps Peak. The system's step pulse timing includes a minimum pulse width and low time of 200 nanoseconds. PDT enhances motor performance by optimizing run and hold currents.

Key Selling Features:
The Silverpak 23D is user-friendly, offers custom motor windings, and features a sleek design. It includes an internal +5VDC output for convenience.

Encoder Option:
US Digital encoders can be mounted externally, with cycles per revolution (CPR) ranging from 32 to 1250 and pulses per revolution (PPR) from 128 to 5000.

Common Tech Support Questions:
Issues such as burned drivers, hot motors, non-rotating motors, excessive current draw, and erratic motor rotation are addressed with troubleshooting tips. Recommendations include checking wiring, using appropriate power supplies, and adjusting speed and acceleration.

Additional Notes:
The document provides guidance on using separate +5VDC sources for optos, handling potential back-EMF, and selecting appropriate decay modes based on motor inductance.

Pin # Function Description 1 & 6 PWR +ve Motor Supply voltage. +15 to 48 VDC 2 & 7 PWR -ve The ground or return of the power supply connects here 3 +5VDC Out Used to ground the logic functions. 4 Step Connects to the open collector drive. 5 Disable This input is used to enable/disable the output of the driver. 6 Opto-Com +5 VDC input used to supply power to the isolated logic inputs. A resistor must be used if the supply is greater than 5 VDC. 7 Direction This input is used to change the rotation direction of the motor. PIN ASSIGNMENTS: p/n 090-00019 ACCESSORIES: Each Silverpak 23D comes with a DB-9 connector with flying leads. A DB-9 female connector cable receives power and provides the control connections for the R208 Driver. Active signals are optically isolated. An open-collector drive is required to provide pulses for Step, levels for Direction and Disable/Enable.

COMMON TECH SUPPORT QUESTIONS / RMA ISSUES: BURNED OR BLOWN DRIVER (LOW INDUCTANCE): Motors with inductance levels of 1.5 mH or less will cause the drivers to blow or not work as expected. Torque will drop because the output current is less than expected. (A limitation of the driver chip) MOTORS ARE HOT: Check holding current and running current. It could be too high. Check wiring. Motor phases could be crossed (A is in B or B Bar, etc) MOTORS DO NOT ROTATE: Check connection between motor and drive. If, for example, the “A” and “A Bar” connection is actually connected to an “A” phase wire and...
