Appendix C Application Notes
Configuration
• [Stop/Brk Mode A], parameter 155
• [Stop/Brk Mode B], parameter 156
– 0 = Coast
– 1 = Ramp
– 2 = Ramp to Hold
– 3 = DC Brake
– 4 = Fast Brake
• [DC Brk Lvl Sel], parameter 157
– 0 = “DC Brake Lvl” – selects parameter 158 as the source for the DC
brake level
– 1 = “Analog in 1”
– 2 = “Analog in 2”
• [DC Brake Level], parameter 158 – sets the DC brake level in amps, when
parameter 157 = “DC Brake Lvl”
• [DC Brake Time], parameter 159 – sets the amount of time that DC
braking is applied after the ramp (if any).
• [Flux Braking], parameter 166 – may need to adjust parameter 549
– 0 = Disabled
– 1 = Enabled
• [Digital InX Sel], parameters 361…366
– 13 = “Stop Mode B” – setting a digital input to this function enables
the use of a digital input to switch between Stop Mode A (open input)
and Stop Mode B (closed input).
