### VH

is a vector variable that defines the H (feedback path) polynomial of the Advanced Pole-Placement velocity controller (COMPMODE = 3). The vector defined by this variable includes four integers that represent the polynomial coefficients, and four shift parameters, one that scales each polynomial. If this variable is changed, a REFRESH command is required.

NOTE: prior to firmware version 2.1.0, this command mnemonic was "H".

SYNTAX: VH [h0] [h0shift] [h1] [h1shift] ... [h3] [h3shift]

RANGE: hN = -2,147,483,647 to 2,147,483,647
