2.5 产品功能 2M2280N 步进驱动器采用了 DSP 单片机作为控制核心，大大地丰富了驱动器的应用功能，同时智能化的固件设计，免去了烦琐的功能设置步聚，让您轻松获得电机的最佳性能！  电机自适应功能：驱动器能够自动检测所带电机的电气参数（如电感与电阻），实时跟

踪电机状态，并根据所检测到的电机状态调节自身参数适应，以达到最佳的驱动效果。如果驱动器不是第一次驱动电机，请先在不接电机线的情况下让驱动器空载启动，此时驱动器会清除以前存储在驱动器内的旧有的电机参数。断电并接上电机线后再重新上电，驱动器会自动测出当前电机的最合适驱动参数。

 相位记忆功能：驱动器在电机断电时，会保存电机断电时的相位。这样可以避免在某些

应用场合下驱动器上电时电机的抖动造成误差。每更换一次电机，或在机器停止后转动电机会使保存的相位失效。

 自动半流功能：在电机停止转动并锁紧 1.5 秒后，驱动器会自动把电机的相电流调整为

当前值的一半，以降低电机的发热，理论上能降低至 25%。

 试运行功能：驱动器设置为此状态时，会自动以 60RPM 的速度驱动电机，此时的电流

输出为设定值，细分设置无效。此功能用于检验驱动器状态是否正常。

 单/双脉冲兼容输入：驱动器的控制信号输入口支持“脉冲+方向” （PLS+DIR）控制信

号及双脉冲（CW/CCW）控制信号输入。

 过压报警功能：2M2280N 驱动器会在内部母线电压超过 395VDC 的时候， 2M1180N 驱

支会在内部母线电压超过 187VDC 的时候，进入高压报警状态。此时应及时切断电源，重新启动驱动器可清除此报警。如果频繁出现过压报警，建议调低输入电压，或采用带吸收功能的驱动器。

 过流报警功能：在电机或驱动器出现短路，接错线等情况下，驱动器会产生过流保护，

以免意外情况下的大电流损坏驱动器，出现过流报警时应及时切断电源，并检查电机的接线。重新启动驱动器可清除此报警。

 欠压报警功能：2M2280N 驱动器在内部母线电压低于 200VDC 的时候，2M1180N 驱动

器在内部母线电压低于 90VDC 的时候，驱动器进入欠压报警状态，欠压报警时重新启动驱动器可以消除此报警。

 过热报警功能：驱动器会在其内部温度达到 75 度时，进入过热报警状态。  错相保护功能：当驱动器与电机间的连线出错时，驱动器会进入错相报警状态，重新按

符合要求的接线方式接线，可以清除此报警。

3.4 控制信号时序图

控制信号注意事项：

 输入脉冲的最高频率为 400KHz。  方向信号禁止在脉冲信号上升期间变化。  脱机信号必须提前脉冲信号 1ms 建立。

驱动器接线注意事项：

 驱动器布线时，为了避免驱动器受到干扰，请遵循强电（电机相线与电源线）与弱电隔

离布线的原则（最少要相距 10 厘米）。

 驱动器的控制信号接线建议采用屏蔽双绞线，屏蔽层必须可靠接地（驱动器与设备的真

实地）。

 驱动器的电机动力线及电源线由于要承受较大的电流，因此建议使用的导体截面积不小

于 1.5mm2，必要时视电流大小选用更大截面积的导线。

 严禁带电接拨线，否则可能造成设备损坏及人身伤害。特别注意电机在锁紧状态，电机

动力线上仍然具有较大的电流，强行接拔线会造成设备损坏及人身伤害。

 电机动力线及驱动器电源输入线接入端子的裸线长度应为 10mm 左右，裸线太短会造成

接触不良，裸线太长有电击危险。电机动力线套上绝缘端子，可减小与端子的接触电阻。

4.2 驱动器及步进电机常见问题及解答

1、步进电机的外表温度允许达到多少?

步进电机温度过高首先会使电机的磁性材料退磁，从而导致力矩下降乃至于失步，因此电机外表允许的最高温度应取决于不同电机磁性材料的退磁点；一般来讲，磁性材料的退磁点都在摄氏 130 度以上，所以步进电机外表温度在摄氏 80-90 度完全正常。

2、步进电机的输出功率怎样计算？步进电机的输出功率随转速变化而不同，一般用力矩来衡量。步进电机的输出功率计算公

式为：P=，其中2n/60，为角速度，为电机此时的输出力矩。

、驱动器的细分功能有什么作用？ 步进驱动器的细分功能是一种电子阻尼技术。有三个明显的作用：

A.因为对步距角进行了细分，因此提高了控制精度。 B.细分是抑制步进电机低频振荡的最好方法。 C.可以在一定程度上提高电机的力矩。

2.5 Product Functions

2M2280N stepper motor drivers adopt DSP single-chip microcomputer as its control core,

which greatly enriches their applications. Meanwhile, the intelligent firmware design frees

the users from complicated function setting steps and delivers the optimum performance

of the motors easily.

 Motor auto adaptation: The driver can automatically detect the

electrical

parameters

(e.g., inductance and resistance) of the motor connected with the driver, trace the

status of motor in real time, and automatically adjust the driver parameters

according to the detected motor status to deliver the optimum driving performance.

If it is not the first time for the driver to drive the motor, please run the driver under

no load before connecting the motor. Then, the driver will clear the motor

parameters stored before. Turn off the power, connect the motor, and turn on the

power again; the driver will automatically detect the optimum drive parameters for

the current motor.

 Phase memory: The driver will keep the phase of the motor in the case

of power

failure with the motor. Therefore, it prevents the error caused by motor jitter upon

power-on on some application occasions. The kept phase will be lost if the motor is

replaced or the motor still rotates after the driver stops.

 Automatic half current: After the motor stops rotation and locks tight, the driver

will

reduce the phase current of the motor by a half in 1.5 seconds to cut down the

heat generated by the motor, theoretically, by 25%.

 Test running: If the driver If the driver is set to this status, it will autoatically drive

2M1180N/2M2280N Stepper Motor Driver

the motor at a speed of 60RPM. At this time, the output current is the set value and

the subdivision setting becomes invalid. This function is used to check whether the

driver status is normal.

 PLS+DIR and CW/CCW compatible input: The control signal input port of

the driver supports “PLS + DIR” control signal and “CW/CCW” control signal input.

 Over-voltage alarm: The driver will generate a high-voltage alarm if the internal

bus voltage exceeds 395 VDC in the case of the 2M2280N driver or 187VDC in the

case of the 2M1180N driver. At this time, turn off the power supply in time and reboot

the driver to clear the alarm. If the over-voltage alarm occurs frequently, it is

recommended that the input voltage be tuned down or a driver with absorption

function be adopted.

 Over-current alarm: The driver will activate the over-current protection function

the

case of short-circuit or wrong wiring of the motor or driver, so as to prevent the damage to the driver. In this case, turn off the power supply in time and check the wiring of the motor. To clear the alarm, reboot the driver.

 Under-voltage alarm: The driver will generate a low-voltage alarm if the

internal

bus

voltage goes below 200 VDC in the case of the 2M2280N driver or 90VDC in the

case of the 2M1180N driver. To clear the alarm, reboot the driver.

 Overheat alarm: The driver will generate a overheat alarm if the internal

temperature reaches 75℃.

 Miss-connection protection: The driver will generate a miss-connect alarm if

the wiring between the driver and the motor is wrong. To clear the alarm, reconnect

the wires correctly.

2.6 Scope of Application

The drivers are applicable to various large and medium automation equipment and

instruments, including engraving machines, labeling machines, cutting machines,

numerical control machine tools, and plotters. They are ideal choices for users in search of

low vibration, low noise, high accuracy, and high speed.

To achieve the optimum performance, KINCO 110 and 130 series stepper motors are

recommended.

3.2 Description of WiringTerminal

Wiring terminals of the driver are divided into three types: control signal port, motor power cable port, and power input port. Control signal port can receive differential signal, single-ended common-cathode and common-anode signals, and can prevent the interference of ambient environment on the driver with the built-in high-speed optocoupler. The twisted pairs are recommended as signal lines for enhanced interference immunity in environments with strong electromagnetic interference. The definitions of the driver ports are detailed below.

Signal

Functional Description

PLS+(CW+)

Pulse signal. In the PLS+DIR control signal mode, the signal is the pulse control signal and the rising edge is effective. In the CW/CCW control signal mode, the signal is the forward rotation control signal and the rising edge is effective. The high-level time shall not be less than 1.25uS to ensure reliable response of the internal optocoupler. The maximum input frequency of the pulse signal is 400 KHz

PLS-(CW-)

DIR+(CCW+)

In the PLS+DIR control signal mode, the signal is direction control signal, and the driver sets the rotation direction of the motor by detecting the level of this signal. The signal value of the effective moment in the rising edge of pulse signal. In the CW/CCW control signal mode, the signal is the reverse rotation control signal and the rising edge is effective. To ensure reliable response of the internal optocoupler, the high-level time in this mode shall not be less than 1.25uS. The maximum input frequency of the pulse signal is 400 KHz

DIR-(CCW-)

FREE+

This signal is offline signal. If the signal is at a high level, the driver turns off the power supply for the motor, and the motor rotor turns into Free status (Offline). Adequate measures must be adopted to prevent the motor from causing equipment damage or personal injury when it is in the offline status.

FREE-

ERR+

Alarm output signal. This signal port is the optocoupler output port for open collector. When the driver has an exception alarm or power failure alarm, this signal port have not outputs((level determined by the external

2M1180N/2M2280N Stepper Motor Driver

Twisted-pair Way Control Signal Wiring Diagram

 The input circuits of all control signals of the driver have been reliably isolated

through optocoupler elements, which minimize the interference from external

electrical noises.

 In the figure, R0 is an external current limit resistor used to curb the input

si gnal

current of the driver. When control signal is at 24VDC, a 2K resistor can be connected;

when the control signal is at 12VDC, a 1K resistor can be connected. The current at

the input port of the driver must be within 6~16 mA; otherwise, the current too less

may cause signal loss,much more current will damage the equipment.

 ERR signal is open collector output and requires an external power supply.

The

maximum external voltage cannot exceed 30V. Never connect the ERR signal port in

reversed polarity; otherwise, it may cause damage to the port.

 if driver work in a strong interference field,the control signal wiring is recommended

twisted-pair way,this can reduce the interference signal source interfere control

signal.

User Manual

3.4 Time Sequence Diagram of Control Signal

Precautions on Control

Signal:

 The maximum frequency of

the input pulse is 400 KHz.

 Disable direction signal

change during pulse signal rise time.

 An offline signal shall be set

up 1ms earlier than a pulse signal.

Precautions on Wiring:

 To avoid interference on

the driver, the strong current cables (phase wires and power cables of the driver) shall be isolated from the weak current cables (for a distance of at least 10cm) when connecting wires for the driver.

 It is recommended that the

twisted pairs be adopted

for control signal cables for the driver, and the shielding layer be grounded reliably (to

the true ground of the driver and equipment).

 Due to endurance of heavy current, conductors with cross-section no less

than1.5mm2 are recommended for the motor cabling, or even thicker ones as appropriate.

Motor cabling put insulated terminals ,it can reduce the contact

resistance between motor and driver.

 It is strictly forbidden to connect wires while the power is on; otherwise, it may

cause

equipment damage and personal injury. Please note that the power line of the

motor

still carries heavy current even if the motor is in the locked status. Pull out or

connect the wire forcibly may cause equipment damage and personal injury.

 The length of bare wires at the inputs of the power line of the motor and the power

input cable of the driver shall be around 10mm; it may result in poor contact if the

length is too short and may cause electric shock if the length is too long.
