HP – Horizontal Power Connector
The HP option on the DMC-21x5 changes the orientation of the 6 pin power connector. By default, the power
connector faces vertically from the board. With the HP option, the power connector faces horizontally.
Part number ordering example:
RA – Right Angle 96 Pin Connector
The RA option on the DMC-21x5 changes the orientation of the 96 pin DIN connector. By default, the connector is
on facing vertically. With the RA option, the connector faces horizontally.
Part number ordering example:
MO – Motor Off Jumper Installed
The MO option on the DMC-21x5 changes the state of the axes when the controller powers on. By default, all axes
are in a servo here (SH) state and in closed-loop control. With the MO option, all axes will be in a motor off (MO)
state when the controller powers on.
Part number ordering example:
TRES – Termination Resistors on Encoder Inputs
The TRES option on the DMC-21x5 adds an additional component to all of the main an auxiliary encoder inputs. By
default, the controller has differential encoder inputs that can also be used with single ended encoders. With the
TRES option, a 120 Ω resistor is placed between the positive and negative differential inputs on the A and B
channels for each main and auxiliary encoder input. This gives the inputs more immunity to noise, however the
inputs can no longer be used with single ended encoders.
Part number ordering example:
D24 and DC48 – DC to DC Converter
The DC to DC option on the DMC-21x5 changes how the controller is powered. By default, the controller requires
+5V, +12V, and -12V supply voltage. With the DC to DC option, only one supply voltage is required to power the
controller. The DC24 option allows the controller to be powered with a single 24V supply. The DC48 option allows
the controller to be powered with a single 48V supply.
Part number ordering example:
Accessory Specific Options
The following options can be added to accessory part numbers. Often, multiple options can be ordered per bank
of 4 axis as long as they are separated by a comma.
ISCNTL – Isolated Controller Power
The ISCNTL option on the DMC-21x5 changes how the controller is powered when using an amplifier or stepper
driver accessory. By default, power is passed from the accessory to the controller; only one power supply is
needed to provide power to the unit. With the ISCNTL option, power is no longer passed through to the controller.
Two power supplies are needed to power the unit, one for the accessory and one for the controller.
Part number ordering example:
SSR – Solid State Relay on AMP-20341
The SSR option on the AMP-20341 changes how current is driven to the motors while axes are in a motor off (MO)
state. The AMP-20341 is a linear amplifier that requires a bipolar power supply. It is possible that the plus and
