5. cting Between Full Half and 1 4 Step The 1030 is configured at the factory for full half or 1 4 step when it is manufactured It is normally not possible to change this setting However if your 1030 was an engineering sample we may have put the step sequencer chip in a socket If this is the case and you want to try a different step mode give a us call we can probably provide you with a different sequencing chip to put in the socket Why would I prefer one mode over another Full step mode will give you the most torque at low speeds Full stepping also allows you to achieve higher speeds than half stepping if the speed of your pulse source is limited For example to drive a motor at 25 rev sec in 1 4 step mode you must supply step pulses to the 1030 at a rate of 20 000 Hz To get 25 rev sec in full step mode only 5 000 pulses sec are required Half stepping is smoother and quieter than full step so you should use half step mode whenever posssible 1 4 stepping provides even more precise positioning and smoother motion than half stepping For special options please call the factory 8 Setting Phase Current The phase current is set at the factory when the 1030 is manufactured The only way to change it in the field is to change the current sensing resistors If you feel that you must change the motor current please follow these rules 1 You must be skilled at soldering to change the resistors You will void your warr

7. e DC power that you provide for the motor This is a low cost and compact technique but does result in some heating of the voltage regulator Don t be surprised if the temperature of the regulator reaches 90 C This will not affect the life of your drive but if you accidentally touch the part you won t be happy You may add a heat sink to the voltage regulator if you wish The metal tab is electrically connected to ground power supply Never use your drive in a space where there is no air flow or where the air temperature is more than 70 C Never put the drive where it can get wet or where metal particles can get on it 12 Connecting the Power Supply If you need information about choosing a power supply please read Choosing a Power Supply located in the back of this manual If your power supply does not have a fuse on the output or some kind of short circuit current limiting feature you need to put a 1 amp slow blow fuse between the drive and power supply Install the fuse on the positive power supply lead Connect the motor power supply positive terminal to pin 2 of the power amp logic connector Connect power supply return to pin 1 Be careful not to reverse the wires Reverse connection will destroy your driver void your warranty and generally wreck your day Pin 2 to power supply Pin 1 to power supply Pin 5 motor A Note if you are using a motor Pin 4 motor A with a shielded cabl
8. hat s because the 1030 uses Switching amplifiers converting a high voltage and low current into lower voltage and higher current The more the power supply voltage exceeds the motor voltage the less current you ll need from the power supply We recommend the following selection procedure 1 If you plan to use only a few drives get a power supply with at least twice the rated phase current of the motor 2 If you are designing for mass production and must minimize cost get one power supply with more than two times the rated current of the motor Install the motor in the application and monitor the current coming out of the power supply and into the drive at various motor loads This will tell you how much current you really need so you can design in a lower cost power supply If you plan to use a regulated power supply you may encounter a problem with current foldback When you first power up your drive the full current of both motor phases will be drawn for a few milliseconds while the stator fields are being established After that the amplifiers start chopping and much less current is drawn from the power supply If your power supply thinks this initial surge is a short circuit it may foldback to a lower voltage With many foldback schemes the voltage returns to normal only after the first motor step and is fine thereafter In that sense unregulated power supplies are better They are also less expensive 11 Recommended Motors Con
