CENTENT CN0165 MICROSTEP DRIVE
2
LOCATION OF COMPONENTS
(1) MOUNTING PLATE
The base plate also serves as a heat sink, although additional heat sinking may be
required. The temperature of the drive must never 70
°
C (+158
°
F). Four
mounting holes on 3.625 inch (92 mm) centers are provided to secure the drive to the
heat sink or the user’s equipment.
(2) OPTION HEADER
A six pin header selects the active
microstep resolution or current profile.
The user jumpers the desired pins with the
shorting bars supplied with the drive.
Eight resolutions or current profiles are
available in each drive. The value for each
selection is printed in the Resolution
Table (see Page
X
14
X
). There are 21
microstep resolutions available for the
CN0165 Microstep Drive.

(3) FAULT LED
This light emitting diode turns on when the CN0165 is in a fault mode. The fault status is
also available on the Fault/Reset Terminal of the connector (see page
X
9
X
). A fault
condition is cleared by shorting the Fault/Reset Terminal to ground potential or by
recycling the power supply (power off, power on).
(4)
TERMINAL CONNECTOR
A 12 position terminal strip provides the connections for the power supply, the motor, the
Current Set and the indexer interface (Step Pulse and Direction inputs). Care must be
taken not to over-torque the terminal screws to prevent damage to the connector.
(5) RESOLUTION TABLE
The Resolution Table provides a diagram of each Option Header configuration, and the
resolution associated with it. A maximum of eight of the twenty-one possible step
resolutions are available in each CN0165.
(6)
CURRENT SET TABLE
This table provides the user with standard 5% values for the Current Set Resistor
connected between terminals 11 and 12 of the Terminal Connector
.
Values are given for
Parallel and Series operation from 0.25 to 20 amps per phase.
(7) OFFSET TRIMPOT
This is a fine-tuning adjustment for high microstep resolutions. It is used to optimize
operation at resolutions of sixteen microsteps or greater.
(8) STANDBY TRIMPOT
This trimpot sets the current level of the CN0165 during periods of motor inactivity.
Standby current may be set from 0% to 100% of operating current.
