LEESON Sub-Micro Dynamic Braking Kit for Ext Resistor - Manual

SUB-MICRO SERIES DYNAMIC BRAKING OPTION (FOR USE WITH EXTERNAL RESISTORS)
INSTALLATION AND OPERATION INSTRUCTIONS
Manual Number: SDBN06C
(These instructions apply to Dynamic Braking modules 174417, 174418, and 174419 ONLY)
The Sub-Micro Series Dynamic Braking option can be used with all SM, SM-Plus, and SM-Basic models.
SM-PLUS SERIES DRIVES
PROGRAMMING
1. Set Parameter 09 (TB-31 OUTPUT) to DYNAMIC BRAKING (04).
WIRING
The diagram to the right illustrates how the DB module is wired to the SM-Plus Series
drive.
NOTE 1: Use 18 AWG wire for control connections.
NOTE 2: Use minimum 14 AWG wire for connections to B+, B-, R+, and R-. The B+
and B- wires MUST be twisted together and must be less than 12 inches
long. Twisting the R+ and R- wires is also recommended.
NOTE 3: External resistors are required when using Dynamic Braking modules 174417,
174418, and 174419. External resistor assemblies are available from LEESON
(refer to the resistor selection chart on the next page).

WARNING!
Remove power from the drive and wait three minutes before wiring the DB module. Incorrect wiring of the B+ and B- terminals will result in
equipment damage! The B+ terminal on the DB module must be connected to the B+ terminal on the Sub-Micro drive, and the B- terminal on the DB
module must be connected to the B- terminal on the Sub-Micro drive.
