INTERFACE (cont'd)
Motor Interface
If armored and shielded cables are to be used, be sure to connect the shield drain or armor to the
ground bus provided in the drive equipment near the output terminals (U, V, W). It is not recommended that
both ends be grounded. Ensure that the motor is connected properly at the junction box and properly
insulated to protect against accidental shorting or grounding.
Speed Sensor Interface (Option)
In addition to open loop control, it is also possible to use a speed sensor to perform high precision
speed control. Speed sensor selection explained below
Resolver
The drive is capable of accepting both 1x and 4x resolver feedback. The excitation can be either 1
or 4kHz. For resolver feedback, the following parameters need to be set:
CS_RES_TYPE=1or4 (Set to match the resolver)
CS_PG_OUT= Set to desired PG output count. (Minimum setting for resolver use is 64)
(See parameter manual for exact settings)
CS_PG_CNT=64
FLG_RES_EX4= 0 for 1kHz, 1 for 4kHz
PG (Pulse Generator)
This drive can read single ended or differential PG signals. The maximum frequency that the PG
input can read is 10kHz for single ended and 100kHz for differential. The PG should be selected so that
these limits are never exceeded. It is recommended that a 10% margin be allowed for overspeed. The
following is an example of how to select your PG.
PG pulse count (PPR) = (maximum frequencyx0.9)/ (application top motor speed (min
<Example> When 100% speed is 1800 min
Max PG pulse count = (10000x0.9)/(1800/60) = 300 PPR
Therefore, PG of 300 PPR or less is used.
The following settings should be used:
CS_RES_TYPE=1
CS_PG_OUT=0
CS_PGCNT = 256 (Set to the PPR of the PG.)
There are three PLG types, a differential type, a single-end totem pole type, and a single-end open collector
type. The connections to the PLG, the jumper setting of XIO brd., and the parameter settings for each PLG
are different.
