Connecting Limit Switches to the BLUAC5 Drives
The CWLIMIT and CCWLIMIT inputs are used for connecting end of travel sensors. By con-
necting switches or sensors that are triggered by the motion of the motor or load, you can
force the motor to operate within certain limits. This is useful if a program or operator error
could cause damage to your system by traveling too far.
The limit inputs are optically isolated. This allows you to choose a voltage for your limit cir-
cuits of 12 to 24 volts DC. This also allows you to have long wires on limit sensors that may
be far from the drive with less risk of introducing noise to the drive electronics. The schematic
diagram of the limit switch input circuit is shown below.
