5605D2 Fully Digital Stepping Driver

A complete stepping system should include stepping motor, stepping driver, power supply and controller (pulse generator). A typical connection is shown as figure 9.

Frequently Asked Questions

In the event that your driver doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the individual components that make up your system and verify that they operate independently. It is important to document each step in the troubleshooting process. You may need this documentation to refer back to at a later date, and these details will greatly assist our Technical Support staff in determining the problem should you need assistance.

Many of the problems that affect motion control systems can be traced to electrical noise, controller software errors, or mistake in wiring.

Problem Symptoms and Possible Causes

Microstep Resolution Selection

When it’s not in software configured mode, microstep resolution is set by SW5, 6, 7, 8 of the DIP switch as shown in the following table:

Current Settings

For a given motor, higher driver current will make the motor to output more torque, but at the same time causes more heating in the motor and driver. Therefore, output current is generally set to be such that the motor will not overheat for long time operation. Since parallel and serial connections of motor coils will significantly change resulting inductance and resistance, it is therefore important to set driver output current depending on motor phase current, motor leads and connection methods. Phase current rating supplied by motor manufacturer is important in selecting driver current, however the selection also depends on leads and connections.  

When it’s not in software configured mode, the first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current. Select a setting closest to your motor’s required current.

Standstill current setting

The current automatically reduced to 60% of the selected dynamic current one second after the last pulse. Theoretically, this will reduce motor heating to 36% (due to P=I2*R) of the original value. If the application needs a different standstill current, please contact Condriver.

Dynamic current setting

Standstill current setting

SW4 is used for this purpose. OFF meaning that the standstill current is set to be half of the selected dynamic current, and ON meaning that standstill current is set to be the same as the selected dynamic current.

The current automatically reduced to 60% of the selected dynamic current one second after the last pulse. Theoretically, this will reduce motor heating to 36% (due to P=I2*R) of the original value. If the application needs a different standstill current, please contact Condriver.

The 5605D2 has two connectors, connector P1 for control signals connections, and connector P2 for power and motor connections. The following tables are brief descriptions of the two connectors. More detailed descriptions of the pins and related issues are presented in section 4, 5, 9.

Connector P1 Configurations

Sequence Chart of Control Signals

In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram:

Remark:

a) t1: ENA must be ahead of DIR by at least 5ms. Usually, ENA+ and ENA- are NC (not connected). See “Connector P1 Configurations” for more information.

b) t2: DIR must be ahead of PUL active edge by 5ms to ensure correct direction;

c) t3: Pulse width not less than 2.5ms;

d) t4: Low level width not less than 2.5ms.

Electrical Specifications (Tj = 25℃/77℉)

Elimination of Heat 

● Driver’s reliable working temperature should be <70℃(158℉), and motor working temperature should be <80℃(176℉);

● It is recommended to use automatic idle-current mode, namely current automatically reduce to 60% when motor stops, so as to reduce driver heating and motor heating;

● It is recommended to mount the driver vertically to maximize heat sink area. Use forced cooling method to cool the system if necessary.

● Anti-Resonance, provides optimum torque and nulls mid-range instability

● Motor self-test and parameter auto-setup technology, offers optimum responses with different motors

● Multi-Stepping allows a low resolution step input to produce a higher microstep output for smooth system performance

● Microstep resolutions programmable, from full-step to 102,400 steps/rev

● Supply voltage up to +50 VDC

● Output current programmable, from 1.2A to 5.6A

● Pulse input frequency up to 200 KHz

● TTL compatible and optically isolated input

● Automatic idle-current reduction

● Suitable for 2-phase and 4-phase motors

● Support PUL/DIR and CW/CCW modes

Applications

Suitable for a wide range of stepping motors, from NEMA frame size 17 to 34. It can be used in various kinds of machines, such as laser cutters, laser markers, high precision X-Y tables, labeling machines, and so on. Its unique features make the 5605D2 an ideal solution for applications that require both low-speed smoothness and high speed performances.
