The IM1007 Driver components are sensitive to ElectroStatic
Discharge (ESD). All handling should be done at an ESD
protected workstation.
Hazardous Voltage Levels may be present if you are using an
open frame power supply to power the IM1007 Driver.
Ensure that the Power Supply output voltage does not exceed
the maximum input voltage of the IM1007 Driver.
WARNING! Do not operate the IM1007 Driver
without a Current Adjustment Resistor!
A resistor MUST be placed between the Current Adjust Input
(Pin 4 on P2) and ground (Pin 5 on P2) to keep the IM1007
Driver and/or motor in a safe operating range.
Do not connect or disconnect power leads or motor leads
when power is applied! Disconnect the AC power side to power
down the DC power supply.
For batery operated systems, conditioning measures should be
taken to prevent device damage caused by in-rush current
draws, transient arcs and high voltage spikes.

Setting Output Current
The Output Current on the IM1007 Driver is set by an external
1/8 Watt or higher resistor placed between Pin 4 and Pin 5 on
Connector P2. This resistor determines the per phase peak
output of the driver. The IM1007 uses a 1mA current source
to establish the reference voltage needed to control the output
current. The relationship between the output current and the
resistor value is as follows:
Output Current (Amps) = .003 x Resistor Value (Ohms)
(See the table below).
WARNING! Do not operate the IM1007 Driver without a
Current Adjustment Resistor!
A resistor MUST be placed between the Current Adjust Input
(Pin 4 on P2) and ground (Pin 5 on P2) to keep the IM1007
Driver and/or motor in a safe operating range.
Automatic Current Reduction
The IM1007 Driver has the ability to automatically reduce the
current in the motor windings after the completion of a move.
The reduction occurs approximately 0.5 seconds after the last
positive edge of the Step Clock Input. The IM1007 Driver will
then revert back to the original current setting at the next
positive edge of the Step Clock Input. To utilize this feature, the
current reference output must be used by connecting a resistor
between Pin 3 and Pin 4 on Connector P2.
