3 SKIP BAND=OFF
OFFSET BAND
G16.3
/ Skip
bandwidth
OFF=0 to
20%
OFF
Sets the skip frequency bandwidth.
For example, if 10% is set, the avoided frequencies will be from
freq(G16.1) – 5% to freq(G16.1) + 5% and from freq(G16.2) – 5% to
freq(G16.2) + 5%. Supposing that the selected range goes from
25% to 30%. In case of the frequency is within that band, for
example 27%, there is two situations:
a)
Drive is accelerating: so the frequency will be increased
up to 27%, but it will not remain here, it will be
increased up to 30%.
b)
Drive is decelerating: so the frequency will be
decreased down to 27%, but it will not remain here, it
will be decreased down to 25%.

1 T DC BRAKE=OFF
DC BRAKING TIME
G17.1
/ Time for
DC brake
activation
OFF=0.0 to
99s
OFF
Allows setting of the time for which the DC brake will be activated.
YES
2 DC CURR=0%
DC CURRENT LEVEL
G17.2
/ Current
applied to the
brake
0 – 100%
0%
Allows setting of the current level applied during braking. The proper
current value must be set to brake the load inertia correctly. If this
value is too much low the load will not be stopped in time. If the
value is too high the power components of the drive will be stressed.
YES
3 DC VOLTS=0.0%
DC BR VOLT LEVEL
G17.3
/ Voltage
applied to the
brake
0.0 – 25%
0.0%
Allows setting of the continuous DC voltage level applied during
braking. The proper voltage value must be set to brake the load
inertia correctly. If this value is too much low load will not be
stopped in time. Otherwise, if the value is too high the power
components of the drive will be stressed.
YES
4 I HEATING=OFF
Idc HEATING
G17.4
/ Non
condensing
heating current
OFF=0.0 to
30%
OFF
Set a suitable value to avoid humidity or condensation forming in the
motor.
Note:
Modify this parameter only if necessary.
CAUTION:
Although the motor is not running there is
dangerous voltage. Run Led will be lit during this process. Be
careful to avoid property damage and personal injuries.
YES

N
User must configure the drive if an external dynamic brake is going
to be used.
OPT
FUNCTION
N=NO
External brake is not used.
Y=YES
External brake is going to be installed.

800 to 810,
OFF=811
OFF
Allows setting of the DC Bus voltage level with which the drive will
activate voltage regeneration control.
