KOLLMORGEN P70360 High Performance Microstep Driver

J6 (motor power supply): 4-pole connector, A+/A - (black/orange), B+/B - (red/yellow) connected to the motor winding, PE (green and yellow stripes) connected to the motor casing, pay attention to the motor direction (swapping A ± or B ± can be reversed).

J7 (AC power supply): 4-pin connector, J7-1 is connected to 120/240 VAC live wire, J7-2 is connected to 240 VAC neutral wire, J7-3 is connected to 120 VAC neutral wire, J7-4 is connected to protective earth (PE), and it is forbidden to connect 240 VAC to J7-3.

J2/J3 (RS-485, R4N version only): 5-pin connector, J2-1/RX+, J2-2/RX -, J2-3/TX -, J2-4/TX+, J2-5/GOS (isolated ground), with 120 Ω terminal resistors connected at the beginning and end of the bus.

Typical wiring scheme

Differential step forward/direction: The controller differential output is connected to J4-1 (STEP+)/J4-2 (STEP -), J4-3 (DIR+)/J4-4 (DIR -), and the cable uses shielded twisted pair, with both ends of the shielding layer grounded.

Open collector electrode single ended signal: The controller's open collector electrode output is connected to J4-1 (STEP+)/J4-3 (DIR+), J4-2/J4-4 are grounded, and an external pull-up resistor is required (when the voltage is greater than 5V, a current limiting resistor needs to be connected in series, the formula R CL=(V s − 5) × 100).

Universal input (such as Jog+): When using an internal 5V power supply, connect J4-14 (DIN5) to one end of the button and J4-20 (Pull Up/Dn) to the other end of the button; When using an external 24V power supply, a current limiting resistor should be connected in series (as above).

Parameter configuration and software operation

（1） Switch configuration (hardware quick setting)

Basic parameter settings can be made through the S1 (motor selection) and S2 (function configuration) switches on the top of the driver, and can be started without software:

Motor selection (S1+S2-1): S1 selects the motor series (e.g. S1=1 corresponds to T21... C series, S1=4 corresponds to N31... G series), S2-1 selects the motor type (OFF is the standard series, ON is CTM/CTP series), CTP motors require additional heat dissipation plates (equivalent to 4.125 × 4.125 × 0.25 inch aluminum plates), otherwise the rated current needs to be reduced by 25%.

Step resolution (S2-2~S2-4): Supports 8 levels of resolution, such as ON/ON/ON corresponding to 200 steps/revolution, OFF/OFF/OFF corresponding to 25000 steps/revolution.

Load inertia ratio (S2-5~S2-7): Set according to the load rotor inertia ratio (0-1 to 20-32), used to optimize anti resonance gain, such as OFF/OFF/OFF corresponding to 0-1, ON/ON/ON corresponding to 20-32.

Function switches (S2-8~S2-12): Dynamic smoothing (S2-8/S2-9), current reduction (S2-10), multi-step (S2-11), locked rotor detection (S2-12), ON is enabled, OFF is disabled.

（2） P7000Tools software configuration (advanced settings)

Software installation and connection

Install P7000Tools (supporting Windows system), connect the PC to the J5 interface of the driver through an RS-232 cable (P7S2-232-9D, RJ12 to 9-pin D-Sub), with a default baud rate of 19200, data bit 8, even parity, and stop bit 1.

After starting the software, scan the drive through "Scan for Connected". For the first connection, configure the node address (1-99) to ensure that there is no conflict with the hardware switch.

Core configuration module

Motor configuration: Select the motor model (or create a custom motor through the "Motor File Editor", enter parameters such as rated current, number of poles, peak torque, etc.), execute the "Probe Stepper Motor" to detect the motor inductance, and optimize the control algorithm.

Mechanical parameters: Set user units (steps/revolutions/millimeters/inches), gear ratio (e.g. 2:1 gearbox set to 2 motor revolutions/load revolutions), and load inertia for motion profile calculation.

Command configuration: Set step resolution (consistent with hardware switch), rotation polarity (reverse motor direction), enable polarity (Active Open/Lost), speed/acceleration/deceleration limits. Jog speed is divided into high and low gears (such as 20 revolutions per second for high speed and 0.5 revolutions per second for low speed).

I/O configuration: Customize 9 universal inputs (such as Jog+/Jog -/EOT+/EOT -/fault reset/start movement), input debounce time (default 1 ms), and universal output functions (such as motor operation/stall/EOT latch).

Advanced settings: Adjust anti resonance frequency (formula)

AResFrequency= 100⋅J Rotor ToothCount⋅T max）、 Dynamic smoothing frequency (formula SmoothingFrequency=9 ⋅ J Rotor ToothCount ⋅ T max), current reduction ratio, and delay.

Sports Profile Generation

Supports 63 independent motion profiles, divided into two modes: AVD (acceleration velocity distance) and T/D (time distance), which can set acceleration and deceleration, target speed, motion distance, delay time, and jump index (chain motion).

Select Profile through "Move Select" input (up to 6 channels, binary encoding). If inputting 1+2 triggers Profile 3, configure "Start Move" input to trigger motion (edge triggered).
