17 (1) Current Limit Max I 30 {%} Max I • When the limit is reached, the drive
displays (Current Limit), and either the
acceleration time increases or the output
frequency decreases.
• Digital outputs can also indicate when the
limit is reached; see P140, P142.
• Refer to section 2.3 for the maximum output
current Max I (%)
DC Brake Voltage 0.0 0.0 {%} 30.0 Setting is a percent of the nominal DC bus
voltage.

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.
p 7 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.

EXAMPLE
If P178 = 29.17 and actual frequency = 60 Hz, then Drive displays 1750 (rpm)

depends on mode of operation.
Refer to section 4.2.
• Other selections choose a diagnostic
parameter to display (P501…P599).
