Velocity Limits at ALL RESOLUTIONS are:
Min = 0.00002 RPS
Max = 100 RPS
Acceleration and Deceleration Limits are the following:
6 LED flashes
(Over Temperature Fault) Internal Fan or Heatsink Tunnel is
clogged or restricted (internal temp.
has exceeded 68° C (154° F). Remove obstruction (clean by blow-
ing shop air through the tunnel.
Ambient air in cabinet is too hot. The Impulse can produce 20 Watts
of heat. If multiple units are installed
next to each other, the cabinet must
be adequately ventilated to remove
heat.
The cooling fan is not turning. Cooling fan is inoperable. Return unit
to factory for repair.
7 LED Flashes
(EEPROM Checksum Fault) At power-up the drive tests the in-
tegrity of its non-volatile memory by
computing a checksum. This fault
indicates an abnormal or defective
condition in the drive.
An error occured during download
or EEPROM write.
The fault can be cleared by issuing a
default configuration from Applica-
tion Developer and then reconfigur-
ing the drive for the target motor. If
the fault recurs, the drive is definitely
defective. The user should not be
able to cause this fault inadvertently
through any combination of com-
mands or actions.
