1 Features
The PANdrive™ PD42-1070 is a full mechatronic solution with state of the art feature set. It is highly
integrated and offers a convenient handling.
The PD42-1070 includes a stepper motor and driver electronics. It can be used in many decentralized
applications and has been designed for 0.20...0.47 Nm max. holding torque and 24V DC nominal supply
voltage. With stealthChop™, the PD42-1070 offers absolutely silent and smooth motor operation for
lower and medium velocities. With spreadCycle™, the PD42-1070 offers a high performance current
controlled chopper mode for highest velocities with perfect zero crossing performance. With stallGuard2™,
a sensorless load detection feature is provided, which is required for using the automatic current scaling
feature coolStep™. The PD42-1070 can be used with a simple step and direction interface and can be
con1gured using a TTL UART interface.
stallGuard2 and coolStep must be con1gured via TTL UART interface and are disabled by default.
