F14 – Stop Method
Factory Setting: “000” [Controlled Deceleration-to-Stop] (with DC Injection
Braking) – F14 is used to select either controlled deceleration-to-stop or coast-to-
stop when a stop command is given. The controlled deceleration function uses a
combination of regeneration and DC injection braking to stop the motor. The facto-
ry setting utilizes regeneration as the primary method of braking. When the output
frequency reaches 1.5 Hz, injection braking takes effect. For high inertial loads, the
optional Brake Resistor may be required (available for Models KBE2-2202, 2203,
4301, 4302, 4303 only). See Section X-D, on page 52. If F14 is set to “000”
[Controlled Deceleration-to-Stop] and a stop command is given, the drive output will
decelerate to the braking frequency set by F16 [DC Injection Brake Start Frequency].
See Figure 18 and descriptions of F15 [DC Injection Brake Time], F16 [DC Injection
Brake Start Frequency], and F17 [DC Injection Brake Level].
F15 – DC Injection Brake Time
Factory Setting: “00.5” (0.5 Seconds) – F15 is used to set the DC injection
brake Time. F15 is factory set to “00.5”, which will apply the DC injection brake
for 0.5 seconds. The brake time should not exceed the actual time to stop the
load since it may cause overheating of the motor. See Figure 18.
Programmable Range: 0 - 25.5 seconds
