p175 DC Brake Time 0.0 0.0 {s} 999.9
NOTE: CONFIRM MOTOR SUITABILITY FOR USE WITH DC BRAKING
DC Brake voltage (P174) is applied for the time specified by P175 with the following exceptions:
• If P111=1, 3 and P175=999.9 the brake voltage will be applied continuously until a run
or fault condition occurs.
• If P110=2, 4…6 and P175=999.9, brake voltage will be applied for 15s
• If P121…P124=18 and the corresponding TB-13 input is CLOSED, brake voltage will be
applied until the TB-13 input is OPENED or a fault condition occurs.
p176 Keypad Setpoint
Single Press
Increment 0.1 0.1 100.0 Used for run screen setpoint editing only.
If P176 >0.1 then scrolling of keypad setpoint
is enabled.
p177 (2) Speed Units 0 0 Hz Select the UNITS LED that will be illuminated when
the drive is running in speed control mode. For this
parameter to be used, P178 must be set to a value
other than 0. IF P178 is set to 0, the Hz LED will
be illuminated regardless of the value set in P177.

p178 Display Frequency
Multiplier 0.00 0.00 650.00 • Allows frequency display to be scaled
• P178 = 0.00: Scaling disabled
• P178 > 0.00: Display = Actual Frequency
X P178
EXAMPLE
If
P178 = 29.17 and actual frequency = 60 Hz, then Drive displays 1750 (rpm)
p179 Run Screen Display 0 0 {Parameter Number} 599 • 0 = Normal Run Screen, this display depends
on mode of operation. Refer to section 4.2.
• Other selections choose a diagnostic parameter
to display (P501…P599).
• Parameters P560 - P564 are selectable if
the sequencer is enabled (P700 is not 0).
P560-P564 are not visible until P700 is
enabled.

Compensation for resonances within drive
p181 Skip frequency 1 0.0 0.0 {Hz} 500 • Drive will not run in the defined skip range;
used to skip over frequencies that cause
mechanical vibration
• P181 and P182 define the start of the skip
ranges
• P184 > 0 defines the bandwidth of both ranges.
p182 Skip frequency 2 0.0 0.0 {Hz} 500
p184 Skip frequency

NOTE
Bandwidth (Hz) = f

= P181 or P182
EXAMPLE: P181 = 18 Hz and P184 = 4 Hz; skip range is from 18 to 22 Hz
p185 Voltage Midpoint
V/Hz characteristic 0 0.0 {V} P165 Valid only when P300 = 0 or 2.
Use with P187 to define midpoint on V/Hz curve.
p187 (2) Frequency Midpoint
V/Hz characteristic 0.0 0.0 {Hz} P167 Valid only when P300 = 0 or 2.
Use with P185 to define midpoint on V/Hz curve.
