JOG SETPOINT Speed the 650 will run at if the Jog input is high,
as a percentage of the MAX SPEED parameter
-100.0 to 100.0% 10.0%
RUN STOP MODE RAMPED : The motor speed is reduced to zero at a
rate set by DECEL TIME (
P
5). A 2 second DC pulse
is applied at end of ramp
COAST : The motor is allowed to freewheel to a
standstill
DC INJECTION : On a stop command, the motor
volts are rapidly reduced at constant frequency to
deflux the motor. A low frequency braking current
is then applied until the motor speed is almost
zero. This is followed by a timed DC pulse to hold
the motor shaft.
0=RAMPED
1=COAST
2=DC INJECTION
0
V/F SHAPE LINEAR LAW: This gives a constant flux
characteristic up to the BASE FREQUENCY
FAN LAW: This gives a quadratic flux characteristic
up to the BASE FREQUENCY. This matches the
load requirement for fan and most pump
applications

FALSE - HEAVY DUTY: Inverse time allows 150%
overload for 30s, then ramps back the current limit
to 105% over a 10s period. At a lower load, the
overload area remains the same, e.g. at 127.5%
load for 60s - after 60s has expired, the output of
the inverse time function is ramped back over a
10s period from 150% as before.
TRUE - NORMAL DUTY: current limit is set to
110% motor current, inverse time delay is set to
30s
When
P
11 is changed from FAN LAW to LINEAR
LAW,
P
12 is set to 0 (HEAVY DUTY)
When
P
11 is changed from LINEAR LAW to FAN
LAW,
P
12 is set to 1 (NORMAL DUTY)
P
12 can be changed independently
0=FALSE
1=TRUE
0
NORMAL DUTY was
previously referred to
as Quadratic Torque
in past Eurotherm
Drives' manuals.
