Note
• P167 = rated motor frequency for standard applications
• P168 default setting depends on drive rating
P169 Accel Boost 0.0 0.0 {%} 20.0 Accel Boost is only active during
acceleration
P170 Slip
Compensation
0.0 0.0 {%} 10.0 Increase P170 until the motor speed
no longer changes between no load
and full load conditions.
P171 (1) Current Limit 200 30 {%} CLim
max
• When the limit is reached, the
drive displays CL , 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 2.2 for CLim
max
P172 Current Limit
Reduction
0 0 Current Limit Reduction
Active - Normal response
In field weakening, the Current Limit
is inversely proportional to the speed.
1 Current Limit Reduction Active
- Fast response
2 Current Limit Reduction
Disabled - Normal response
3 Current Limit Reduction
Disabled - Fast response
P173 Decel Override
