4.4 Initial setting of the resolver angle
• The resolver angle should always be set without having suspension ropes installed.
• If the ropes are installed, the recommended unbalance is 50 %. Allowed unbalance is
30...70 %.
• If ropes are installed, the LWD must be adjusted before setting the resolver angle.
• If no ropes, parameter
(5_1) must read L 50. If parameter (5_1) does not read L 50, select
parameter
(6_74) and set value to -1 and press select. Default value for the software
based LWD scaling is 50 %.
