Emotron VSB Instruction Manual Chapter 6 Specification of Parameters
b1-15 DC brake current Range: 0.0% - 100.0%
Factory default:
b1-16 DC brake time Range: 0.00s - 30.00s
Factory default:
During the process “ramp to stop + DC braking", DC brake would be started when output
frequency attains set value of b1-14. b1-15 defines brake level, in amps, applied to the motor.
100% corresponds to rated current of drive. B1-16 sets the length of time that DC brake current
is “injected” into the motor when b1-13 is set to 2. In case brake time is set to 0.0s, DC brake
shall be disabled.
If "DC brake stop" terminal enabled, time length of this terminal or b1-16 set time
(whichever is longer) would be taken as stop brake time.
0: Disabled
1: Enabled
When overexcitation brake is enabled in case of stop by Decel, the motor shall transform the
electric energy generated during Decel into heat energy by increasing magnetic flux so as to
attain rapid stop. If this parameter is enabled, the Decel time will be shortened. If
overexcitation brake is disabled, the Decel current of motor will decrease and the Decel time
will be lengthened.
0: Disabled
1: Enabled
When dynamic brake is enabled, the electric energy generated during Decel shall be
converted into heat energy consumed by brake resistor, so as to attain rapid Decel. This
brake method applies to brake of high-inertia load or the situations that require quick stop. In
such a case, it is necessary to select appropriate dynamic brake resistor and brake unit.
b1-19
Dynamic brake
Range: 325V~375V
Factory default:
Dynamic brake
Range: 650V~750V
Factory default:
When b1-18 is set to 1, when the bus voltage reaches the value set by b1-19, the energy will be
consumed by externally-mounted brake resistor, to guarantee the fast stop. This parameter is
for brake effect setting, according to application requirement.
