M542 driver, mainly for driving 42 series, 57 series and some 85 and 86 series of two-phase hybrid stepping motors. The motor has a lower heating temperature, noise and higher running smooth performance. Micro-step breakdown of the number of 15 species, the maximum number of steps is 25000Pulse/rev, operating peak current range of 1.0-4.2A, output current total of eight files, the current resolution of about 0.45A, with automatic half current, overvoltage, overcurrent protection. DC power supply, recommended operating voltage range of 24-36V, the voltage must not exceed 50V, the minimum can not be less than 20V.
Mainly used in various small and medium sized automation equipment and instruments, such as: a variety of engraving engraving and milling machine, CNC cutting machine, marking machine, laser engraving machine, packaging machinery, automated assembly equipment. With low prices, low noise, fast speed


Operating Instructions:

Set the number of micro-step

By the SW5-SW8 four DIP switches to set the number of micro-step drive, and its total of 15 stalls micro-step. User Settings micro-step, you should first stop the drive to run. Micro-step breakdown of the number of specific settings, the drive surface layout instructions.

Output current setting:

Three by the SW1-SW3 DIP switch to set the driver output current, the output current total of eight files. Specific output current setting, the drive surface layout instructions.

Automatic half current function:

Users can set the drive through SW4 automatic half current function. off indicates dynamic current quiescent current is set to half, on the static and dynamic current of the same current. General purpose of SW4 should be set to off, the motor and the drive to reduce fever, increased reliability. Burst about 0.4 seconds after the cessation of current is automatically reduced to about half (60% of the actual value), is theoretically reduced to 36% of heat.

Signal Interface:

PUL + and PUL-for the control pulse signal positive terminal and a negative terminal; DIR + and DIR-direction signals for the positive terminal and a negative terminal; ENA + and ENA-enable signal to the positive terminal and a negative terminal.

Motor interface:

A + and A-phase winding A stepper motor connected to the positive and negative terminals; B + and B-B-phase stepper motor windings connected to the positive and negative side. When A, B two-phase windings exchange, can make the motor direction is reversed.

Power Interface:

DC power supply, recommended operating voltage range 20-50VDC, Power greater than 100W.

Indicator:

Drive has two indicator lights red. The green power indicator which, when the drive is powered up after the green light; red as a fault indicator, when an overvoltage, overcurrent fault, the fault lights lit. The fault is cleared, the red light is off. When a drive fails, only the power on again and re-enabled in order to clear the fault.

Installation Instructions:

The dimensions of the drive: 118 × 75.5 × 34mm, mounting hole spacing 112mmmm. Both horizontal and vertical installation, we recommend the use of vertical installation. Installation should fit snugly against the metal cabinet to facilitate cooling.
