11.2 A: Initialization Parameters
582 YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual
Analog Input FilterTime Constant
When b1-01 = 1 [Frequency Reference Selection 1 = Analog Input], it adds noise to the analog frequency
reference during run.
• Minimize the effects of noise.
• Change H3-13 [Analog Input FilterTime Constant] to a range of 0.01 s to 0.10 s.
Startup Current Check
When you do a test run, set L8-41 =1 [High Current Alarm Selection = Enabled] and use U4-13 [Peak Hold
Current] and a clamp ammeter with the machine under load and not under load to check the motor current during
start up.
If the motor torque is not sufficient during start up or if the timing between the motor and the holding brake is
unsatisfactory and causes the motor to lock, a large quantity of current will flow. In these conditions, adjust the
parameters again and decrease the load to decrease the current to less than 150%. If the current flow is more than
150% of the drive rated current, the heat stress on the IGBTs will decrease the service life of drive parts.
To decrease the effects of heat stress, decrease the carrier frequency of the drive to 2.0 kHz to 2.5 kHz for
applications where low audible noise is not necessary.

Note:
• Settings for A2-01 to A2-32 vary depending on the value selected for A1-06 [Application Preset].
• You must set A1-01 = 1 [Access Level Selection = User Parameters] to access parameters A2-01 to A2-32.
