KOLLMORGEN P70360 High Performance Microstep Driver

Basic Information

Core positioning: P70360 is an AC input micro stepper driver that supports 120/240 VAC power supply, with a maximum output current of 2.5 A RMS (peak 3.5 A RMS) and integrated Dynamic Smooth ™ (Dynamic smoothing) Multi-Stepping ™ (Multi step) Encoderless Stall Detection ™ (No encoder blockage detection) and other patented technologies should be used in conjunction with Kollmorgen recommended stepper motors (such as T2x/N3x/K3x series), and parameter configuration can be achieved through switches or P7000Tools software.

Version iteration: The document has undergone 7 revisions (1-G version), with the latest G version mainly updating outdated pin numbers, adding J4-18 pin warnings, updating brand logos, and revising the motor selection section to ensure compatibility with firmware version 2.10 and above.

（2） Hardware features and optional configurations

core functionality

Dynamic Smoothing ™）： The second-order low-pass filter reduces motion impact and mechanical resonance, and sets the smoothing level (minimum/moderate/severe/aggressive) through S2-8/S2-9 switches.

Encoder less Stall Detection ™）： By monitoring the deviation between the instruction position and the actual position through the internal motor model, if the deviation exceeds 2 full steps, a fault will be triggered and activated through the S2-12 switch.

Current Reduction: After the motor is stationary for 100 ms, it automatically reduces the current to 75% of the rated value (the ratio and delay can be adjusted through software), and the S2-10 switch controls enable/disable.

Multi Stepping ™）： Enhanced filtering function, smoothing low resolution input (such as 200/400 steps/rev) into micro step output, with S2-11 switch enabled.

Model difference

P70360-SDN: Basic version, only supports step/direction control, default universal input configuration is Jog ±/EOT ±/fault reset.

P70360-PNN: Advanced version, supporting step/direction and indexing functions, with additional MV SEL 1-4 inputs for multi speed selection.

P70360-R4N: Equipped with RS-485 communication version, supports multi machine networking (requires unique node address configuration), and adds J2/J3 connectors for RS-485 bus.

Hardware installation and electrical wiring specifications

（1） Mechanical installation requirements

Installation preparation

Installation surface: It should be a cold plate (recommended aluminum), fixed with 8-32 or M4 screws, and the driver should be installed upright (with the heat sink fins facing left), leaving at least 25.4 mm (1 in) of heat dissipation space around to avoid direct exposure to heat sources.

Temperature control: When the temperature of the heat sink exceeds 70 ° C, the driver will overheat and shut down. If the ambient temperature exceeds 40 ° C, it is necessary to increase fan cooling or reduce the load duty cycle.

installation dimensions

Basic version (without RS-485): Length 170.18 mm (6.700 in), Width 132.21 mm (5.205 in), Height 52.324 mm (2.060 in).

Equipped with RS-485 version: length 170.18 mm (6.700 in), width 132.21 mm (5.205 in), height 58.217 mm (2.292 in).

（2） Electrical wiring specifications

Wiring safety and sequence

Power off operation, ensure that the drive capacitor is discharged (after power off for ≥ 2 minutes, measure the DC bus voltage<40 V), all power cables and control cables need to be separately shielded, and both ends of the shielding layer should be grounded.

The distance between the power cable (motor/power supply) and the control cable (step/direction/I/O) should be ≥ 20 cm to avoid cross interference; When the cable length exceeds 25 meters, Kollmorgen 3YL-20 choke coil is required (such as SERVOSTAR 601-606 with 4 × 1 mm ² cable).

Core connector definition

J4 (26 pin command I/O): includes step (J4-1/2), direction (J4-3/4), enable (J4-5/6) inputs, fault output (J4-7/8), 9-channel universal input (J4-10~18), universal output (J4-21/22), and 5V power supply (J4-19/25).
