Dual coil PCPs
Short circuit to ground
Mode selection (current or voltage) and full scale
current ranges
Do not connect a digital output to battery+ (back drive) without a series diode.
PLUS+1 PWM output circuits are not designed to be used as inputs. Output current feedback readings
should be used for fault checking only.

Warning
Unintended movement of the machine or mechanism may cause injury to the technician or bystanders.
The module will be powered up if battery voltage is applied to the module's output pin. To protect
against unintended movement, secure the machine.
C
Caution
Warranty will be voided if module is damaged by significant current driven back through an output pin.

Comment
The current may accidently be
exceeded in open loop mode. If the
current exceeds the trip point, the
output will be latched off.
Depends on load characteristics.
Some pins have a fixed frequency,
consult module application program
interface (API).
Increased in steps, see module API.
Increased in steps, see module API.
There is over-current protection built
into each output driver. If the
instantaneous current exceeds the
trip point, the driver is latched off.
