Current Limit Max I 30 {%} Max I • When the limit is reached, the drive
displays CL(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 (%)

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.
