Datasheet
LED Fault Codes: Two LEDs give a status indication with either a solid color or a blink-blink-blink-off status code. A tertiary LED
will only light in the event the fuse blows and is labeled on the PCB as “FUSE” above the LED as seen in Figure 1. The Status LED
codes can be found below:

APPENDIX
This is a small section dedicated to using the GR214V that did not fit in any specific section of the manual.
HEATSINKING CONSIDERATIONS
As with all stepper motor control the GR214V will create heat while operating. The drive can be thermally modeled as a 0.25
ohm resistor for I
2
R heating calculations. The heatspreader plate on the drive is a hard anodized piece of aluminum and will
electrically isolate the drive from anything it is connected to. When heatsinking the GR214V any piece of aluminum may be
used without need for isolating kapton or a silpad. We recommend using thermal paste on the bottom of the heatspreader to
ensure proper thermal transfer. If your motor is rated for 3A or below an external heatsink is unnecessary.
The most important aspect to heatsinking is proper airflow. A small fan can provide significant circulation in most systems and
should blow over the fins of any heatsink that is used. Adjusting the standby current trimpot can significantly impact your drive
and motor heating at idle, so for non-load-bearing applications (i.e. a vertical axis) it is recommended to adjust it to 70% or less.
ENVIRONMENTAL RATINGS
The GR214V is rated for commercial use, with an operating temperature range of 0C – 75C (32F – 167F) and a humidity range of
0 – 95% non-condensing. Use in environments outside of those ranges are not advised but Geckodrive support can recommend
workarounds in some cases.
REPLACING THE FUSE
Replacing the fuse on the GR214V can be done quickly in the field. The fuse plugs into two sockets and can be removed with
tweezers, pliers, or by hand. The part number for the fuse is 0251007.MXL and it will need its leads formed at the same
distance as the sockets, cut to length and pushed in. Make sure that the fuse resists being pulled out at both ends to ensure a
proper fit.
